Restoration of janitors. How can I restore the wiper brushes: we consider different ways

Operation of the machine in conditions of poor visibility - this is what drivers vehicle Fight constantly. Depending on weather conditions (snow, rain, etc.) Overview of the space in front of the windshield of the car can deteriorate significantly, which contributes to the creation of an emergency on the road. At the same time cleanliness windshieldSupported by windscitches of the car, in everyday life of the wipers, has an important meaning and largely depends on the state of the latter.

Causes of poor quality windows

Having found that when working janitors, layouts remain on the windshield of the machine, it is necessary to check their condition and determine the causes of poor quality cleaner.

Quite often the reason for the appearance of divorces on the windshield of the machine is:

• ground windshield, which will not be able to clear the best windshield wipers;
• loose fit of elastic brushes to the windshield;
• malfunctions of metal parts of the windscreen wipers;
• wear of the cleaning edge of the elastic element of the brushes.

The reasons that caused the poor-quality work of the wipers may be due to:

• long-term contact of fixed brushes with windshield machines (deformation of elastic parts) under the influence of direct sunlight or with a strong frost;
• hitting the mud into the grooves of the elastic tape of wipers;
• in the grooves of water brushes with its subsequent freezing;
• a change in the chemical structure of elastic parts under the action of ultraviolet radiation (direct solar rays);
• wear of the working edge of the elastic tape;
• the appearance of corrosion trash tape on the blades.

Restoration of janitor

Noticing that the brushes began to purify the windshield to the windshield, car enthusiasts, as a rule, try to replace them with new ones. However, this is not always justified, since in some cases Restore the performance of janitors on the car is not a lot of work. For example, if during the operation of the machine, it was found that the working edge of the brushes is strongly worn, it can be restored using sandpaper.

For this:

1. Take a sheet of negligent material (multi-layer plywood, a fairly thick sheet of metal, etc.).
2. Printed a strip of fine-grained emery paper on it.
3. Conducting the cleaning blade of the janitor on the sandpaper, restore the ribbon form, giving the working edge a rectangular shape.

Important! It is necessary to closely ensure that the restored work surface of the wiper across the entire length of the tape turned out to be uniform. The presence of failures on it will lead to the fact that during operation on the windshield, the machine will remain wide uncleaned bands.

If the elastic tape of the janitor has hardened, then gasoline can be used to restore it. Dipping the tape into gasoline, then washed it in warm water and applied a thin layer on the working surface silicone lubricant. These procedures will be returned to the tape elasticity and make it softer.

Tip! Using silicone lubricant, you can also restore the performance of janitors for a short time, in which there are minor cracks on the work surface, causing scraping or creak during operation.

The working surface of the janitor was covered with an oily film, it is possible to restore its properties (degreased), for example, Using White Spirit. White spirit will easily remove fat and other contaminants from the surface of the brush. After this procedure, it is desirable to apply a thin layer of silicone lubricant onto the working surface of the glass wipers. Thus, it will be restored. How to restore the wipers by car Experienced motorists can be seen on:

In the same way, you can remove from the working surface of the wiper and corrosion traces.

Attention! When working with White Spirit, it is necessary to comply with the elementary safety regulations (ventilated room, gloves, etc.).

Care for windshields

Automotive wipers, like other components of the machine, require regular maintenance. In order to extend the "life" to the branches on the car, experts recommend:

• regularly clean the windshield of the machine and the working surfaces of the wipers from dust, dirt and fat deposits, and in the winter season from snow and ice;
• shoot the wipers if the car remains on the street for a long time;
• leaving the car in the garage, lift the wipers in such a way as to eliminate the contact of the elastic surfaces with the windshield (the distance to the windshield should be at least 5 mm);

It is extremely important in the winter time of the year to turn on the wiper only after the ice on the windshield car melts.

Wiper (janitor) in the car - This is an electromechanical device with a rubber brush, which serves to remove water and dirt from the windshield.

Invented a wiper in 1903 English Engineer James Henry Apjohn. And only in 1916 wiper began to install in mass production cars.

When the first signs of bad work of the janitor appears, in the form of a strip on the windshield of the car or insufficient transparency of the glass in the form of a thick water film after the passage of the wipers, many motorists replace brushes with new ones, not even trying to figure out the poor work of janitors. More economical motorists do not fit rinse the rubber ribbon brushes with soapy water and clean the surface of the glass from the dirt. Often it helps, but if the brush is already worn, then flushing and wipes do not help, even if there is an effect from such prevention, then for a short time.

Device and principle of operation of a frame brush of the janitor

If the metal or rubber frame of the janitor does not have serious mechanical damage, then such a brush can be repaired with their own hands. To fully repair the repair, the device and the principle of operation of the wipers of the car wiper should be.

Device frame brush

The main part of any car janitor is a rubber tape, since from its quality and technical status It depends on the cleanliness of the windshield of the car in bad weather.

Rubber tape for effective water removal is made quite elastic and two elastic plate springs are used to fasten it in the janitor. The plates in length are equal to the length of the rubber ribbon and are inserted from the two sides to the grooves specifically provided for this.

At the ends of the elastic plates, rectangular samples are made, and at the base of the tape are the same in the form of a protrusion. Thus, fixation of plates in rubber ribbon, excluding their movement, is ensured.

The brush frame is a few rocker uninunted interconnected with axes. The number of rocker depends on the length of the brush and there are them in the frame from three to seven pieces. The axes are fixed in rivet ribs.

For better mobility, plastic liners are inserted between them, which reduce the wear of the rockers and exclude the creaking when working as a janitor. In the middle of the longest rocker, the axis is pressed for fastening the plastic adapter for it - latches.

Adapters are needed for the possibility of installing the brush of the janitor on the leash (lever) of the wiper of any car model. Usually, new brushes are equipped with a set of the most demanded adapters suitable for almost any car windscitus. To fix the adapter on the rocker, it is enough to dress it on the axis and with an effort to press it on it. The adapter securely fixes on the rocker. Before installing the new adapter, you need to determine which of the set is suitable for your wiper. You can use the old adapter, removing it with the native brush that has spent its resource.

The length of the rubber ribbon depends on the size of the brush of the janitor. But the profile of tapes for janitors of different lengths and structures, including frameless brushes, is almost the same. True, there are ribbons that have additional sharp edges on the side surface, but this is already excluding, I have not seen them on sale.

On the photo of the profile, the tape is clearly visible three symmetric grooves passing along its entire length. The upper groove is designed to be installed in its elastic spring plates, which give the rubber tape elasticity and shape. In the middle grooves, the foot clips of the risk clamps are coming, including and fixing. The lower groove forms a neck of the tape and provides the possibility of shifting the working part of the rubber ribbon while changing the direction of movement of the janitor during the cleaning of the car windshield from precipitation and dirt.

Device frameless brush

Frameless brushes of janitors are rarely applied and due to these high cost and narrow use. Each brush is manufactured for a certain narrow range of car models. They are not universal.

Frameless brushes differ from the framework that instead of the rocker system, a flat wide spring-loaded metal plate is used, on which brackets of the janitor's tape holders are fixed with rivets.

The shape of the forming plate is made according to the form of windshield of a particular car. Therefore, they are not suitable for any model. This wide tape is closed with a rubber casing glued to it, making cases of disruption of the joints of the hinges, like a skeleton brush. The design of the rubber ribbon and the principle of its work when cleaning the glass does not differ from work in a frame janitor. In the frameless janitors, there is also an opportunity when wearing to replace the rubber tape, as in the skew janitor.

Principle of operation of the brush of the janitor

Removes water from the surface of the windshield of the car's brush brush thanks to the special form of the working part of the rubber ribbon. The photo of the ribbon is recorded in the photo when the brush is moving the brush from Lev to the right, in the direction of the blue arrows.

As can be seen, the working sheet of rubber tape is slightly flawed in such a way that its direct angle is perpendicular to the glass plane. Thus, a wide part of the ribbon cannon removes a thick layer of water. The remaining thin film of water, pushing it to the glass, removes the straight ribbon angle.

When changing the direction of the brush, the working part of the rubber ribbon of the brush of the janitor is shifted and already pushes a thin layer of water another straight corner of the tape. Thus, the janitor's brush carries out the windshield of the vehicle with direct and reverse course. The remaining water remnants after the passage of the brush in the form of a micron film due to scratches on the glass and entering small mechanical particles quickly evaporate and glass becomes transparent.

If during the work of the janitor working part of the ribbon or part of it takes the position relative to the surface of the cleaned glass, differing from the photographs shown in the photographs, then the car glass will remain opaque or water stripes will remain.

Causes of poor car windshield cleaning

Now knowing the device of the janitor and the principle of operation of the rubber ribbon, it will be easy to figure it out independently why the brush has become badly cleaning the windshield from the water and try to restore it before buying a new one. The poor job of the janitor is manifested in the form of the remaining bands after the passage of the brush or opaque, the turbidity of the glass, which makes the driver who impede the driver overview during the ride.

The first thing is necessary with the unsatisfactory work of the janitor to do, it is removed from the surface automotive glass Dirt, oil film and check the frame of the janitor. The mobility of the rocker in the places of their additions and the absence of breaking, the reliability of fixing the adapter and the wiper lever in it, the adequacy of the effort created by the spring clips of the wiper lever. In winter, water is often in the articulation of the rocker, water freezes, freezes and their mobility is lost. If the frame is in order, the brush audit should be conducted.

On the windshield of the car
After the passage of the janitor remains stripes

The brush leaves the strip of water on the glass due to the incorrect adjacent of a separate area, or several, working part of the rubber ribbon to the glass surface at the level of the left bands. At the same time, the strips of the brush can be left only directly, only on the opposite or at both directions of the brush movement. Strips may remain in the middle of the passage of the brush or along the edges. Causes, depending on the place of leaving the brushes, the strips are different.

The brush began to leave the stripes on the glass suddenly

If the janitor worked normally and suddenly began to appear the bands when moving into one of the sides, then the mechanical particles in the form of sand or dirt came in the groove of the rubber ribbon, which do not give the working part of the tape to bend, and the edge of a direct angle does not become perpendicular to glass. In winter frost, it is possible to get into the groove of water and its subsequent freezing. It is enough to remove the dirt out of the edge, and the brush will earn normally. The ice can melting itself from the heat of the windshield, heated by warm air blowing from the inside of the cabin, or the ice is necessary from the groove of the tape gently so as not to damage tightly tapes, remove the sharp item.

If the strips suddenly began to appear in the middle when the brush of the janitor is moving in both directions, it is possible that the ingress of dirt and ice in the grooves of the tape from both sides and the loss of the ribbon from the retaining flat spring plates. This happens in winter. If the brush approached the windshield and it was pulled off, pulling away from the glass for the rocker, without waiting when the glass warms up, the ice melts and the brush is free.

As can be seen in the photo, the plate came out of the rubber ribbon rubber, and the ribbon lost linearity. Therefore, it is unacceptable to dypipe about the brush for the rocker, if there is no time to wait, then you need to gently move the ribbon along the glass with a scraper. This malfunction of the brush is not difficult to eliminate even without removing it from the car. You must first put in the groove the elastic plate on one side of the rubber ribbon, and then the screwdriver blade to start the plate in the groove on the other side.

Stripes on the windshield after the passage of the brush
Expanded gradually

If a narrow strip appeared when the janitor first appeared, and then for a long time - days, weeks gradually expanded, it means that the cause of the malfunction is most likely due to the wear of the rubber belt of the brush. As a result of aging in places of bending, rubber ribbons, usually cervices, cracks appear, and rubber in these places rushes, more often on the edges of the brush. The tape continues to break and the zone of the bands increases.

The photo shows a brush with a torn rubber ribbon along the cervix line from the unfinished end. Such a ribbon recovery is not subject to and should be replaced with a new one. If the non-torn part of the rubber ribbon clears the glass is still good and the brush tape broke from the unfinished end, then it can be reused by setting a shorter brush to the frame.

With a serviceable ribbon, the bands can still appear when the brush moves, slowly expanding, with the wear of one or more hinge connections among themselves. Then the tape, when changing the movement of the janitor, it is not always shifted, and the water remains on the glass. In this case, the brush, when moving, can jump over the glass.

When the wipers are not included, the brushes under the action of the spring of the wiper leash are pressed with a rubber ribbon to the glass. At the same time, the tape along the neck is bent. From the effects of temperature with time, the rubber is deformed, which leads to the inability to take the ribbon the working position when the janitor is turned on.

The photo is clearly visible deformation of the rubber ribbon, the working part was deformed on the left side. With the onset of greater deformation, although the working angles are not yet worn, the tape will not be able to shift and fully purify the glass from the water.

Another enemy of automotive brushes is time. Even if the brush almost did not work, for example, the car was not exploited for a long time, or new brushes, lay in stock for several years, rubber aging, it loses elasticity. The refined rubber tape can not change the direction of movement of the brushes to shift and purify the glass of the car from water. To check the elasticity of the tape, it is enough with a little effort to take to the side of the finger and let go. The tape should be easily deformed and instantly return to its original position.

It remains to consider the last reason for the poor work of the wipers, the wear of the working edge of the rubber ribbon. Usually, with intensive operation of the car, the brushes have to work a lot, removing water from the windshield, along with dust and sand grains. Sometimes, even a solid dirty story. This form should have a working edge of a new rubber tape. As you can see, the working edge has a rectangle shape.

The windshield of the car during operation is covered with numerous small chips and scratches. Thus, over time, from friction about grain chips and scratches on the glass, regardless of the manufacturer and quality of the rubber ribbon, its working edge is spinning, ceases to urge the water film and glass after the passage of the brush, it remains not transparent enough. Straight corners in the worn edge of the rubber ribbon are captured and take the look as in the photo below.

Typically, the brush is still in good condition, but with the worn corners of the working edge of the rubber ribbon, replace the new, without thinking that the rectangle can be restored by a simple reception, with the help of sandpaper, driving the rounded part from the working surface of the ribbon.

Repair of automotive brushes

If it is determined that the cause of the working capacity of the car janitor is to wear the working surface of the edge of the rubber ribbon, then it is possible to restore it, without even removing, the janitor with a wiper leash. To do this, take a plate of a negligent material, for example, a multi-layer plywood and stick a sheet of the same size of fine-grained emery paper. The plate will be larger in length, the better the edge will be better.

The main thing when performing this work began to complete the rubber tape evenly along the entire length, in order to prevent failures, otherwise in these places when the janitor can remain on the glass.

It is even better to perform grinding rubber tape by gluing the sandpaper on the plate, in length exceeding by 10-15 cm the length of the brush itself. Then work will be done much easier with the best end result. After each multiple passes, it is necessary to check the result to be direct corners and not to restore excess rubber, as it is still useful in subsequent repairs. In this way, the ribbon can be restored several times.

If the rubber tape has finally become unusable, and the frame is still in good condition, it is advisable to replace it new. It is possible to replace the use and torn from the movable side along the cervix line used by the rubber tape, removed from a longer brush. It is not difficult to remove the rubber ribbon.

First you need a screwdriver blade a little to the side of the retainer retainer of the rubber ribbon.

Rubber tape is removed from the paws of the ribs. Elastic plates are removed from the tape. Sometimes the elastic plates are curved, and it is necessary to remember which way to adopt in the groove of a new rubber tape. Sometimes samples in the plate are smaller than the protrusions in the ribbon groove. Then you need to properly fit the samples in size.

A new rubber tape prepared for replacement is made by a groove through all fishery support fixtors. The tape should freely, but without a backlash, move along the rumor. If any of the support does not provide free moving or tape in it too free, then it is necessary, respectively, sliding the paws or squeeze them.

After refueling the rubber tape of the janitor in the foot of the rocker supports, it will remain pliers to compress the lock and the brush is ready for installation on the vendor of the car wiper.

As you can see, spending only ten minutes you can give the second life with a brush. Especially relevant to such repairs for expensive branded janitors.

How to choose brushes for wipers wipers

First that length brusheswhich must comply with the requirements of the car manufacturer. If the brush is shorter than it is supposed, the glass cleaning area will decrease, which will lead to a decrease in the road viewing angle. In the case of a larger length, the pressure per unit of the length of the rubber ribbon will decrease and the spring of the leash is insufficient to press the rubber ribbon of the water layer and the glass after passing the brush may remain non-transparent after passing.

Next need to check whether adapterMounted on the brush purchased or the presence of additional adapters for leashes your car. The most common type of fastening of janitors to a leash is a "hook". Usually all brushes are equipped with an adapter for him.

The third criterion is tape quality. At its planes, especially on the working, borrowers and irregularities are not allowed. The tape should be elastic, homogeneous texture and color. The working edge must have a straight angle along the entire length of the tape. The same requirements for the tape are presented when it acquires it for the restoration repair of the brush. Ribbons in expensive janitors are silicone, graphite-silicone and teflon, they are more resistant to wear, as they have a reduced friction coefficient, but also the price of them several times higher than tapes from rubber.

It remains to check the frame and the freeness of the movement of the tape in the root of the rocker. The rocker in the hinge joints must necessarily be with plastic liners and there should be no backlash, but the freedom of movement of the rumor relative to each other remains. The tape should freely move freely in supports, except for its extreme fixing. It is easy to do, pulling the ribbon to the brush of the janitor from the frame.

In the three storyline roller, it is shown how in practice, check the freedom of moving the brush of the janitor in the supports. On the first plot of the tape overly clamped in the supports of the risk or the dirt was stuffed, such a brush requires repair or replacement. In the second and third plots, respectively, the response of a properly fixed rubber ribbon in the rocker is a short and long brush. According to the oscillations of the rubber ribbon, it can be seen that the necessary freedom of moving the ribbon in supports is available.

Many polemical conversations are underway on manufacturers of brushes for a wiper, but in any case all the brushes are made in China. Only brand are produced under the supervision of well-known firms. To find out for a fake or not, unprofessional is difficult. Therefore, it is necessary to rely on an external inspection. If the brush of the janitor or the repair tape meets the above requirements and pleases external species Your eyes are likely to suggest that it is high quality and last long. Such a brush and should be purchased for your car.

Do it yourself and at least for a while. We use proven means and extend the service life of the wiper brushes.

Grease gasoline

The effect is short-term, suitable for the "killed" brushes, which are no longer a pity, but there is no time to buy new. Graphite spraying collision with gasoline will survive badly, and after all it is responsible for the quality of sliding on the glass and the absence of a screap. So writing the "janitors" in gasoline only as a last resort. Again, after evaporation of gasoline from rubber, the condition of the brush will be even worse.

Note! After wetting gasoline, the brush must be washed with warm soapy water.

Lubric silicone

Slip will be too cool as the world champions in figure skating! Accordingly, the quality of the cleaning of the glass on the contrary will decrease sharply.

Lubricate "White Spirit"

Good liquid, and the effects of it are interesting. Only work with this solvent should be carefully, putting the means of individual protection and in a well-ventilated room. Again, the effect will be short-term, and old brushes to the new "White Spirit" will not turn.

Lubricate glycerin

The usual pharmacy glycerin "can" soften hardened rubber. Before applying the brush you need to clean from dust and dirt, and then wash and dry. After applying glycerin to the surface he is allowed to absorb.

Wash in hot water

Water with a temperature of 50-60 degrees remove the surface layer of fat from rubber. However, to keep the brushes in the water half an hour, and the effect will last very long.

Restore the shape of the brush

If the working surface of the brush is extended, then extend the life of the accessory and return the cleaning properties can be sandpaper. We take a plate of a negligent material (durable plywood, for example), glue the fine sandpaper and gently handle the rubber edge of the brush so that it becomes rectangular. The method has drawbacks: if the surface is unevenly handled, there will be wide strips on the glass.

Secret Method of Mysterious Grandfather

On the steamer Drive2 there is a post about a special Dedovsky method of restoring wiper brushes. It will take "White Spirit" (gasoline solvent) and several cigarettes. It is necessary to get tobacco from cigarettes and shake it on a rag moistened in a solvent. After that, wipe the cloth with a cloth. The author of the method assures in an unusually powerful effect from tobacco, but it is better to check his words again on old brushes.

For security at any trips by car is important to be good review. And the wipers play in this not the last role, or rather their serviceable work. For which it is worth a timely prevention and purification of the engine cleaner mechanism. But if it happened that the wipers refused, you can try to correct the problem yourself. But not every motorist has such skills, assistance in this situation will provide a qualified specialist - auto electrician.

Design mechanism of wipers.

The modern glass purification system was invented in 1903, and many different designs were invented over the past time. But great popularity among car manufacturers won the Tandem scheme, more practical and efficient. The structure of janitors uses a generally accepted technology:

- the electric motor attached to the gearbox is responsible for the clearer movement of janitors,

- The trapezium, using the lever system, creates a reciprocating movement, and regulates the synchronization of the brushes.

- the mode of operation controls the switcher relay, which is controlled by the steering switch or on-board computer. And if the auto rain sensor includes a car, it is possible to adjust the janitors to provide automation.

- Almost brushes are replaceable in the design of any janitors, which is attached to the latch lever. The adapter can be like a non-removable part of the brush and separate. For greater efficiency in the work of the wiper, it is necessary that the brushes are pressed to the glass with a certain force. This feature is performed proper adjustment Leads, which is performed when replacing the wiper.

Also, the wiper system can be vacuum or mechanical. They are usually used to control the rear wiper.

Simple or composed repair of the mechanism of wipers.

Initially, it is worth checking if the fuse has burned down, since very often the wipers refuse to function precisely because of this. If everything is fine, with the help of the tester, contact all contacts, thereby eliminating the possibility of cliffs in the wiper mechanism power grid.

You are lucky if the cause of the breakage can be eliminated by the usual replacement of janitors or fuse. But as the practice shows the repair of the wiper mechanism is not a simple task. To deal with a serious malfunction for only a qualified auto electrician. This concerns repair or full replacement The trapezium, or the rear wiper in general. Specialists of our company will help to cope with problems of various difficulties, repair wipers with any drive system, providing a service for repairing quality and quickly.

The reasons for not the correct functioning of the wind or rear window cleaning system are much, and only a competent auto electrician can help in their elimination. Let's tell about it in more detail:

1. The appearance on the glass of the longitudinal stripes indicates the dirt that fell under gum brushes. If after washing the problem is not eliminated, it is required to replace the wiper.
2. The reason for the occurrence of spots of small size is most likely a deformed gum. Such a breakdown also leads to a complete replacement of the aggregate.
3. If the wiper electric motor does not work, there may be several reasons for this:

- Deformation of the trapezium

- Finding foreign items in the mechanical elements of the wiper

- closure of winding in the electric motor

But it happens, there are situations when the breakdown occurs on the road, or it is simply not possible to deliver the car to the service. In this case, the service of the call electrician services are very convenient. The specialist of our company in the shortest time will arrive at the location of your car, will diagnose the causes of the breakdown and produces required repair. After that, advises how to avoid what happened next time.

In no case, do not attempt to repair independently such problems. This can lead to more severe consequences, as the repair of electricians of the car there are many nuances and features.
