Lada brake fluid Kalina. Replacing brake fluid with your own hands Lada grant brake brake fluid for Lada 4

We recommend choosing a class of fluid that AvtoVAZ recommends, that is, DOT-4. To determine the brand or manufacturer, you can rely on the reviews of car owners VAZ. According to a survey, about 66% of car enthusiasts buy the brake fluid of RosDot Dzerzhinsk. And not in vain, because in the tests of the magazine "Zarul" he is in good positions:

1. SINTEC EURO DOT-6 (CLASS 6)
2. RosDot 6 Dot 4 (Class 6)
3. Sintec Super Dot 4
4. LUKOIL DOT 4.
5. Hi-Gear Dot 4
6. RosDot 4.
7. Sibiria Super Dot 4
8. Rosa 4.
9. Felix Dot 4.
10. Vitex Dot 4.
11. RSQ Professional Euro Dot 4
12. Himluux Dot 4.
13. UNIX DOT 4.
14. Prompack Dot 4.

Test results DOT-4 brake fluids. All brake fluids of the same class are compatible with each other. Do they differ from each other? The answer to this question give experts "driving."

* More - better. ** less - better.

Is it possible to mix dot-3, dot-4, dot-5 or dot-5.1

Differences of classes brake fluid:

• DOT 3 (glycolic base) - for relatively low-speed cars with drum brakes or disk front brakes;
• DOT 4 (glycolic base) - on modern high-speed cars with mainly disk brakes on all wheels;
• DOT 5.1 (glycolic basis) - on the road sports carswhere thermal loads on the brake are significantly higher.
• DOT 5 (Silicone) on ordinary vehicles Practically do not apply.

Brake fluids DOT 3, 4, 5.1 (color from light yellow to light brown) are interchangeable, but it is not recommended to mix them (better to perform full replacement), Properties can deteriorate. DOT-5 (Dark red) Mix it is impossible, it is mixed only with himself. In other words, brake fluids can only be mixed in colors.

And what brake fluid can you recommend? Is it worth changing the familiar class DOT-4 for others, for example, DOT-5.1? Recall that you can easily find any information about your car (Niva, Priora, Kalina, Grant, Largus, Vesta, Xray).

ROSDOTOT-4 brake fluid was designed specifically for cars with disk brakes, taking into account the recommendations of AvtoVAZ specialists. Romdot-4 today is one of the best in its class among world analogues. It is recommended to replace the brake fluid after 1.5-2 years. This is due to high levels Her hygroscopicity. When using Romdot-4, it is not recommended to top up another brake fluid, as this will lead to a deterioration in the properties of RosDott-4, and, as a result, a decrease in the efficiency of the braking system.

Technical characteristics of brake fluid

Useful advice
In order for the future to be unforeseen expense on repairing the braking system, or even the whole car Lada Grant in general, replace the brake fluid in a timely manner. It is very hygroscopic and absorbs moisture from air, which, in addition to the emergence of corrosion of the components of the brake system, lowers the boiling point of the fluid itself, and this may lead to brake failure with frequent intensive braking. Do not use the brake fluid to merge from the brake system: it is dirty, saturated with air and moisture.
The brake fluid entering the wires, plastic or painted body parts can cause their damage, so always put the clean cliff with the fill. If liquid gets into this part, you immediately wipe them with a clean cloth.

1. Check the level of the brake fluid in the main brake cylinder tank. When the plug was removed, it should be between the MIN and MAX labels deposited on the tank housing. With a plug, the level of the brake fluid should be at the lower edge of the bulk neck, since the brake fluid is displaced by the level of the level sensor.
A WARNING
A gradual decrease in the level of the brake fluid in the absence of leaks indicates, most likely, on the need to replace the brake pads. Check out the condition of the brake pad (see "Checking the degree of wear of the brake pads, brake discs and brake drums") on the Lada Grant. The late replacement of the brake pads leads to expensive repair (replacement of brake pads, brake discs and brake drums)!

According to the map technical inspectionThe replacement of the brake fluid on Lada Priora should produce every 45 thousand km of run or once every 2 years. Over time, in the process of operation, the fluid loses its properties, which affects the efficiency of braking. The brake fluid that has spent its resource has a dark shade, while the new - light shade.

What brake fluid to choose for priors

The manufacturer fills DOT 4. The most popular buyers have RosDot 4 brake fluids and NEVA-M. The first option is more expensing the second cheaper. For cars with ABS and it is recommended to use different types of liquids.

• Dot-4 Plus - for cars without ABS
• DOT-4 Class 6 - Developed for Modern Brake Systems (ABS, ESP, VSA)

Depending on the container, the cost of the brake fluid indicated above from 50 to 150 rubles.

You can also pour DOT 5.1 liquid. It has a lower viscosity than the above samples, as well as more high temperature Boiling and applications for manufacturers changes once every five years.

Lay a liquid different types prohibited!

Replacing the brake fluid on the Lada Priora do it yourself

For replacement, it will be necessary:

• Actually the brake fluid itself
• To remove the old liquid syringe
• dry rag
• tableware for old liquid
• rubber hose, the diameter of which must be under the sloping fittings on the wheels
• Special brake key 8 by 10 mm

Now pour a new brake fluid into the tank to the MAX level.

Now it is necessary to completely remove the old fluid from the pumping system and fill in the new liquid.

Sequence of pumping brakes on the prior

1. Rear right caliper
2. Caliper rear left
3. Front right caliper
4. Saliper front left

It is in such a sequence that the brake system should be pumped

Pumping brake system with your own hands

Each wheel has a special drain fitting to remove air from the brake system. It is through it that needs to be removed air and an old liquid.

A rubber hose prepared for the fitting and descends into the dishes to drain the old liquid. At the same time, the hose in the dishes should be also in the liquid so that there is no air suction.

Using the brake key, we repeatedly unscrew the fitting on each wheel and pump the old liquid from the system until it becomes clean. You will need an assistant who will have to swing a brake pedal, your task to lower the old liquid.

That is, the assistant shakes the brake pedal 5-10 times and pursues it. You unscrew the fitting, drop the liquid. The assistant shakes the pedal again, then presses you again merge the liquid. And so you need to do with each wheel.

Watch while pumping the brakes behind the liquid level in the tank, it should not be empty.

After pumping, make sure that in the tank the brake fluid is on the mark between MIN and MAX. On this, the replacement of the brake fluid on the Lada Priora is completed.

Work performed on the viewing ditch or overpass.

We turn off the cover of the tank the tank.

Pump the old tank liquid with a syringe or rubber pear.

Pour a new brake fluid into the tank.

Attention! Brake fluid that fell into paintwork, plastic parts and car wiring, can cause damage. Immediately remove it with a clean rag.

It is necessary to pump the hydraulic engine of the brake system until the new fluid (brighter than old) fails to extend from the bumps of pumping of all workers cylinders.

Pumping for the replacement of fluid, we carry out when the engine is not working first on one contour, and then on the other in the following sequence:

• brake mechanism right rear wheel;
• brake mechanism left front wheel;
• brake mechanism of the left rear wheel;
• brake mechanism of the right front wheel.

Before pumping, check the level of the working fluid in the tank of the brake hydroplaring. If necessary, plunge the liquid.

Pumping brakes spend with an assistant. Cleaning from dirt pump fitting brake mechanism Right rear wheel.

Remove the protective cap of the rear right wheel with the rear right wheel cylinder.

The assistant should vigorously press the brake pedal until it stops 1-2 times and keep it pressed.

The key "On 8" turns into a 1/2-3 / 4 rolling fitting.

At the same time, liquid will flow out of the hose, and the brake pedal should be harvested until it stops.

As soon as the liquid stops flowing out of the hose, wrap the fitting, and only after that the assistant can let go of the pedal.

We repeat this operation until a new brake fluid comes from the fitting (brighter than old).

We remove the hose, wipe the bleeding fitting and put on it a protective cap.

Remove the protective cap from the bleeding mechanism of the left front wheel.

We wear a hose on the fitting, and its free end is immersed in the container, partially filled with working fluid.

We pump out, as described above, the brake mechanism of the left front wheel, turning the fitting of pumping the key "on 8".

Similarly, pump the brake mechanisms of another contour.

When pumping, you need to monitor the fluid level in the tank and, if necessary, to add liquid.

After pumping the hydraulic drive of the brakes, bring the level in the liquid in the tank to the norm.

There is an even simpler version of the brake fluid replacement. This method does not require the presence of an assistant. In this case, some brake fluid supply is desirable (at least 1 liter).

Install the car on the viewing ditch or the flight and provide a free passage between the place where you can replenish the tank with brake fluid in open space, and brake cylinders of all four wheels.

Pump a rubber pear or a syringe brake fluid from the tank. Take a new liquid to the upper edge. To accelerate the process (in order to produce liquid from all cylinders at once), it is desirable to choose four cuts of tubes that wear all cylinder pumps tightly. The free ends of the tubes are lowered into transparent bottles of a small container.

We turn out the fittings of all brake cylinders. We are convinced that the liquid flowed over all four tubes. Control the decrease in the liquid from the tank located on the brake cylinder, and immediately replenish the tank. We observe the rise of the level of liquid in bottles located near the wheel brake cylinders.

It is necessary to move several times from the position of the observation of the fluid from the brake cylinder fittings to the position when you can check and replenish the fluid level in the tank located on the brake cylinder to prevent the tank drainage.

Usually the fastest level increases in the bottle, which is lowered the hose coming from the front left wheel brake cylinder. As soon as in the bottle of the front left wheel, about 200 ml of fluid will turn out, we wrap and tighten the fitting of this cylinder. Next, we are waiting for the same result at the front right wheel cylinder, and also wrapping his pumping fitting. You can complete the process after a 200-250 ml of liquid will be released through the fitting of each rear wheel.

We are convinced of a hermetic tightening of all fittings. Wear protective caps. We specify the level of fluid in the tank of the main brake cylinder.

Lada Grant car has a brake system (pipelines, brake cylinders, a vacuum amplifier, brake control, brake pads, etc.) similar to the car Lada Kalina. For efficient and safe braking in Lada Grant, a diagonal, two-circuit pipeline system is applied, this means that the first circuit blocks the wheels - the right front and left rear, and the second outline is the left front and right back. On the front wheels are installed disc brakesThe rear drum brakes are installed. The main brake cylinder management occurs through a vacuum brake amplifier, which increases the efficiency of the operating system by the brake system by pressing the brake pedal. Depending on the configuration of the car Lada Grant brake system It can be equipped with an anti-lock brake system (ABS). On the car Lada Granta is available hand brakewhich blocks rear wheels (brake pads breageble pads). The pads are bred through the lever system, moving the steel cable fixed on the lever located in the car. Vacuum amplifier by car Lada Grant (shown in Fig. 1) of the diaphragm type. The diaphragm is a separating partition between the discharged atmosphere created in the vacuum amplifier and an external atmospheric pressure. Pressure difference reduces effort on brake pedals. When the brake pedal is released, the vacuum and atmospheric chamber communicate with each other through a special valve.

Pumping the hydraulic drive of the brake system is carried out after its repair, which caused the disruption of the system's tightness and, if he suspected from entering the air system. In the latter case, you must first determine and eliminate the cause of air in hydraulic drive And only then proceed to his pumping. The presence of air in the hydraulic drive of the brake system is determined by the behavior of the brake pedal: it becomes soft (the emphasis is not felt at the end of the pedal stroke) and falls below its usual position.

To fulfill the work, you will need an assistant as well:

Special wrench for pumping fitting or clay key for 8 mm;

Transparent vinyl tube of suitable diameter;

Capacity for draining brake fluid;

Lookout ditch or overpass (preferably).

We prepare the car to work.

Disconnect the wiring harness block from the sensor connector insufficient level brake fluid and remove the tank cover

To avoid air from entering the hydraulic drive of the brake system while pumping the drive, make sure that the level of the brake fluid in the tank did not fall below the mark below Min.

If the rear axle of the car is posted (the car is on the lift or installed on the stands), the pressure regulator will block the path of the brake fluid to the rear wheel cylinders, so for pumping rear wheelscylinders need to open the regulator valve.

To open the pressure regulator valve insert the blade of the slotted screwdriver between the lever and the plate, with the blasting of the regulator.

9. Pump the brake mechanisms of the other wheels if necessary.

In the absence of air in the system, the brake pedal must be "tough", i.e. Pressing no more than half of the distance to the floor.

Replacing the brake fluid

To fulfill the work, the assistant will need, as well as rubber pear.

1. Prepare the car and the necessary equipment to perform work.

2. Remove the tank cover

To avoid air from entering the hydraulic drive of the brake system during the replacement of the brake fluid, make sure that its level in the tank does not fall below the mark MIN..

3. We selected pear liquid From the main brake cylinder tank.

4. Pour a new liquid into the tank to the top edge of the tank.

5. Pour the contours of the hydraulic drive system, starting with the rear wheels of the car.

6. Pumping each wheel cylinder before the start of the release of a new (lighter) brake fluid from the fitting.

7. After replacing the fluid in both circuits, we check the operation of the hydraulic line and bring to normal the fluid level in the tank of the main brake cylinder.

Replacing the brake fluid in the brake hydraulic system modern models Lada (grant, Kalina, Priora, Niva 4x4, Vesta and Xray) must be carried out every three years or after 45,000 km of run (depending on what comes before). Lada Largus - every six years or after 90 thousand km. Run. All cars have a similar design of the brakes, therefore the process of replacing the brake fluid is similar.

Replacing the brake fluid (method number 1)

Traditional, all familiar method for replacing the brake fluid in the hydraulic system of the brakes by substitution. Procedure for pumping for modern cars Lada (grant, Valina, Priora, Largus, Vesta and Xray) - rear right, front left, rear left, front right wheels. For Niva 4x4 - rear right, rear left, front right, front left.

1. Pump liquid from the tank (syringe or rubber pear);
2. Pour a new brake fluid;
3. Remove the protective cap from the brake fitting, weaken the tightening of the fitting with the key and wear the hose (the other end is immersed in the container of half filled with liquid).

To force the brake fluid to flow out of the fitting, the assistant will need, which should be 1-2 times on the brake pedal, and then hold it with the foot. Instead of an assistant, you can put the strut or create pressure in the tank using a special lid or lungs (closing the mouth with a rag). Such methods of pumping brakes without helper we considered earlier.

As soon as instead of the dark fluid, it will run brighter, go to another wheel according to the circuits (see above). Periodically check the level of brake fluid in the tank and, if necessary, pour it, otherwise the air will fall into the brake system.

Replacing the brake fluid (Method No. 2)

On certain cars (for example, Lada Vesta, Largus, Xray with French boxes JH3 / JR5) there is a simpler way to replace the brake fluid - use a fitting for pumping the clutch. There is less time, but the brake fluid will be replaced only in part.

We dress the hose on the fitting (the other end is immersed in a container of half filled with liquid). Next, the pipeline should be depicted, for this we lower the bracket down (No. 4) and pull out the plastic tube (№1, right) by 7-9 mm. We drain about 150 ml of fluid (with or without an assistant, see above) and back seal the contour. Check the level of brake fluid in the tank. This process is in detail.

Recall that the brake fluid that fell into the paintwork, plastic parts and car wiring can cause their damage. Immediately clean the surfaces from the brake fluid. Do you change the brake fluid with your own hands? What difficulties were under the first replacement? By the way, do you know which brake fluid is better to choose?

Cut the prevention of the brake circuit together with the partner, alone "pumping" the system is extremely difficult. To ensure maximum access to the contour, use the viewing channel or roadside overpass.

Step-by-step instructions for replacing brake fluid on Lada Vesta

1. Machine is installed in the perimeter of the repair area.
2. We unscrew the wheel.
3. Clean the work area of \u200b\u200bthe hub from dirt.
4. The partner pumps the brake pedal.
5. Fixes it in the lower position, holds.
6. At the hub, unscrew the tvavelitz.
7. We descend (blending) excess DOT liquid.
8. We again pump the pedal.
9. Repeated air.
10. We replenish the missing amount of DOT.
11. We repeat the pumping procedure as needed.

Where is the brake caliper

In the cars of the family Lada Vesta, the Tavodnitsa is located on the brake caliper. Expansion tank for drawing dot - in motor compartment, in the right part.
The regular location of the caliper, the tvotnice on each of the wheels is identical.

Liquid replacement resource. The consequences of the diversity of time

Avtovaz engineers recommend updating DOT every 45,000 km. In practice, the interval is reduced to 35 - 40 thousand km due to the poor quality of the fluid.
Effects undime replacement Dot can be different, up to an emergency.

Signs of need for replacement

• reduction in braking efficiency;
• increasing the brake path;
• increased free pedal stroke;
• tightness of the stroke, the small informativeness of the pedal;
• on the dashboard Signals a malfunction indicator in the brake circuit;
• brake fluid level below the minimum permissible in expansion tank.

Sequence of actions during self-replacement of fluid

Required tools, materials:

• key to "10", "14", balloon on "17";
• rag;
• additional lighting;
• Dot for fill;
• new brake pads as needed.

Algorithm of actions:

1. We post the machine with an electric lift.
2. Open the hood.
3. Unscrew the lid of the expansion tank of the brake fluid.
4. Remove the wheel.
5. In the cabin, the partner pumps the brake pedal, fixes it in the lower position. Waiting for the team.
6. From the back brake caliper We clean the surface, remove the dirt, wipe dry.
7. The key to the "10" we unscrew the tvotnutska, whip air together with the liquid.

1. Spin, give the command to the partner to repeat the pumping procedure.
2. We repeat the step again.
3. We replenish the missing amount of dot in the expansion tank.

After completing the pumping of one wheel, immediately proceed to the following scheme:

• Front left - rear right;
• Front right - rear left.

The algorithm indicated above does not allow to replace dot in the circuits. The design of the car is such that without a capital dismantling "rinse" is impossible.

Many Motorists STRs use a hydraulic channel to replace the brake fluid:

1. From the front of the motor, we find a hydraulic fitting.
2. Remove the plastic cap from it.
3. We put on the hose, one end of which is lowered into a container with liquid.
4. We blend a bracket.
5. Put the plastic tube.

1. The system was depicted, dot under pressure flows from the hose.
2. As soon as the level in the expansion tank falls below the minimum, we replenish the missing number.
3. We repeat the procedure of cleansing until the dot color becomes transparent.

The volume of dot, which is poured into Lada Vesta - 1.5 liters.
