Tuning car brakes in terms of safety and efficiency. Alteration of the brake system

Are there such owners who are absolutely all arrange in their car? You can relate differently to tuning, but if there is anyone who never wanted to improve the headlight, to put "music" more abruptly or add "horses" to the engine. All this is usually feasible, but before you begin to improve the dynamic characteristics of your car, you should teach it ... to slow down, and it is effective. Pay attention to such a vital, literal and figurative sense, part of the car, like brakes, follows and those who are not interested in the installation of speed records, but it does not quite satisfy its functioning, poor responsiveness and low sensitivity. Today it will be about such a topic as a brake tuning.

How does the brake system work

The brakes were used on the means of movement for a long time, long before the vehicle appears, and during the existence of its very much this system did not change fundamentally. Consider briefly the brake system of the car and how it works. You can select 2 main parts.

1. The braking drive, which includes:

· Pedal.

· The main brake cylinder (GTC).

· Pipeline system.

· Amplifier.

· Wheel brake cylinders.

2. Brake mechanism, there are two types: disk and drum.

The principle of operation of the system is such. Pressing the brake pedal affects the GTC. The piston installed in it moves and increases the pressure of the brake fluid in the system of pipelines, which was supplied to each wheel. The liquid presses on the pistons of the caliper, which pressed the brake pads to the disk and, due to mechanical friction, the car stops.

Causes of the inefficiency of the brake system

What if the performance of the standard brake system does not satisfy, or are it planned to improve the characteristics of the car as a whole? In any case, the brake tuning is where it will not seem strange, it is necessary to start all work.

Modernization of the brake system can be carried out in different ways, based on the purposes set. Consider 2 typical cases: when it is necessary to simply improve the convenience and ability of the car to extinguish the speed for conventional operating conditions, and a significant improvement in the characteristics for fans of a dynamic ride, especially if you plan to increase the engine power or increase the mass of the car.

Easy tuning

Those who prefer a calm driving style, but not satisfied with how brakes work, you can advise to replace regular brake discs on the larger diameter models and, possibly, more thickness, which will help improve the ventilation and cooling of the disk. Accordingly, it will have to install and enlarged caliper, because Old may not approach the new disk. The presence of perforation and grooves on the surface of the brake disc under normal conditions, most likely, no benefit will be given, but in difficult weather conditions, when water, dirt, stenched reagents fall on the disk, these additional holes will help to cleanse from such Mud film and restore reliable disk and pads.

Due to the fact that the larger caliper is used, the area of \u200b\u200bcontacting the pads with the surface of the disk increases, which means that the braking efficiency will increase. New shoes should be selected with the best frictional characteristics.

Deep tuning

In the event that a whole range of works with a car is planned, among which the engine is refined in order to increase its power, making changes to the suspension, transmission, etc., those work that lead to an improvement in the speed indicators of the car, the simple replacement of the disks can not do. Speed \u200b\u200blovers, active driving style need sports brake systems.

Similar work is carried out and then when the mass of the car is significantly increasing, for example, when booking. Such modernization is useful for escort and accompaniment machines, the efficiency of the braking system of which is important for the performance of its functions.

For such tuning brake system, you will need:

· Set the effective perforated brake disc of large diameter with increased thickness and notches for good cooling and cleaning from mud and water film.

· Set a large caliper with 4, 6, 8 and more pistons to achieve high characteristics due to the large area of \u200b\u200bthe contact spots of the pads with the surface of the disk and the uniform distribution of their press on the disk.

· Replace regular brake hoses on reinforced to eliminate their inflating with an increased pressure in the hydraulic highway.

You may have to use wheels of larger diameter and tires with improved coupling properties. Owners of powerful sports cars can consider the option of installing ceramic discs, durable, lungs, best working at high temperatures.

What to install

For tuning brake system, we offer to buy Frando brakes manufactured for installation on many models of cars of all popular brands. This Taiwan manufacturer is little known with us, but is engaged in the release of exclusively brake systems for cars and motorcycles since 1993 and has international certificates ISO-14001 and TS-16949. This manufacturer started his way from the production of brake systems for railway rolling stocks. The sets produced them are high-quality products, differ in variety of models and dimensions, low price.

Security car

The ability of the car quickly accelerate, move at high speed, to be obedient in turns - important, but, perhaps, even more important is the ability to quickly and effectively slow down. The life of not only those who are in the cabin, but also others depends on it. Attentive attitude to the performance of the brake system is confidence in the car that manage, confidence in the safety of yourself and others. Even a light tuning is cheaper than body repair, and the costs of nerves, time and forces are generally not estimated at all. Watch your car, and let his stop extens the brake system intended for this.

Extremely large number of accidents happens due to loss of vehicle management. Improving brakes is vital when the engine is raised and in love for high speeds.

What is the first step towards improving the braking system?

Initially, it is recommended to study the braking system and its device. It is worth starting with shifts of pads and disks on sports options. The pads are best acquired with enhanced composition designed for our purposes. Let them do not exist so well with a calm movement due to the requirements for prior warming, but perfectly support their properties with sharp braking. During a dynamic ride with regular and rather sharp brakes, such pads are not susceptible to overheating and demonstrate reliability.

With disks, the situation is similar. With factory, you need to purchase ventilated discs, with holes. In the brake, they are not subject to overheating, which will extend their performance. For better efficiency, it is recommended to use discs from another car with larger dimensions. Braking will be better when increasing the area of \u200b\u200bcontact between the disk and the block.

Acquisition of notched ventilated discs for example on the site http://superbraks.ru and, while, saving on the pads, quickly leads to dot dudes. Expellations advise adhere to one manufacturer in this matter, because the material will be the same type and balanced according to its data (minimum wear at the maximum coefficient of friction).

The further step will be the installation of a more powerful vacuum amplifier. What it will be more powerful, the faster there will be a brake reaction. Options in this issue will be the purchase of a modified vacuum amplifier of a large size or use from another car. The installation of such equipment is important when improving the brake system and when braking at high speed, its work is noticeable. The effects of brakes will require less effort on the pedal.

It's time to shift our drum brakes to the disk. The advantages are:

At temperature growth, the indicators are quite stable.

Temperature resistance of disks is higher as an improved cooling ability.

Braking has greater efficiency, which gives to reduce the time of braking.

Smaller dimensions and weight

Growing brake sensitivity.

Reduced response in time.

The order of seventy percent of the energy of the moving machine is reduced by the front brakes. At the same time, the rear brakes give a reduction in the front.

Basically, in the presence of a car, the process is not simple with rear-wheel drive. The disadvantage is the search for a solution to upgrade the handbrake. You have to change the hub, install the caliper, install the hoses instead of the tubes, mount the disk and adjust the pressure sensor. The rear-wheel drive car imposes some difficulties - the replacement of the bridge is necessary. It is much easier to find a suitable bridge from a vehicle.

Improve brakes only can not be restricted. Interestingly, rubber hoses are subject to stretching or blown. Since they are somewhat "walking", the efficiency of the brake system is an order of magnitude less, and the gas pedal has to be pressed. In order to avoid such consequences, the hoses of the reinforced type are used.

Next level of improvement - replacing additional components. This refers to the minting of multiple mechanisms. The process requires significant changes, but in the end there is a completely replaced braking mechanism, which is clearly affected by the result.

Warning: intervening the work of factory brake mechanisms is prohibited. After such fractions will have to forget about honest technical inspection. Do not forget that besides this tuning may be unsafe for life.

Periodically, on tests of even new cars, we face that the regular braking system sometimes behaves wrong as we would like. If it is easier - brakes are missing. Moreover, the scatter of cars to which claims arise, does not depend on the cost and prestige of the brand - there is something to chite and Chinese brands, and even luxury British. Another category of potential customers is the owners of used and domestic cars, which are often ready to pay extra for better and expensive components. About professional and even street riders and not to say: they have special requirements for the characteristics of the machine. As a result, it turns out that improving the brakes is a potentially requested service. And what does it represent and how really needed? Let's try to figure it out.

The main tasks in the brake system tuning two: an increase in braking speed and a reduction in the brake path. For each correspond to individual parts, so first of all it is worth understanding that the improvement of the characteristics of the braking process is a comprehensive procedure requiring a solid, which means competent and therefore the cost approach.

Depending on what we want to get at the exit, you can take a deep tuning of the brake system or partial. This question must be posed in advance.

Of course, you can change the brakes in stages: first the rear, then the front. You can replace only discs or calipers. By and large, it all depends solely on the solvency of the customer. But, one way or another, everything in the complex must be changed to achieve the result.

The first, where to start, are brake discs.

Brake discs

The regular is made of high-strength cast iron with a high friction coefficient and a low degree of wear; With intensive use, for example, in a metropolis, or with regular trips along the highway, during braking, they can often overheat, which eventually lose the initial characteristics, and even come into disrepair. Particularly carefully consider the disks to the owners of powerful age cars.

The modern industry offers several types of tuning brake discs, each of which has its advantages and disadvantages.

Ventilated discs

Externally, such a disc resembles two glued separate disks separated by the blades of the airlows. Empty space promotes ventilation, allowing air to pass through the disk during rotation, cooling it. The ventilated discs have a stronger design. Most often, they are used when tuning the brake system. True, the manufacturers are increasingly putting ventilated discs on modern cars.

Perforated discs (with transverse drilling)

Repel water, gas, cooled and contribute to the removal of dirt and nagar particles. Discs with transverse drilling have one drawback - with time, cracks and dorms appear around the drilled holes. In addition, small holes are clogged with mud and nagar.

With notches

Such discs repel water, gas and heat, contributes to the removal of particles of dirt and nagar, and also matches the brake pads. Installed on sports cars - mainly in order to divert dirt and nagar. When working, makes more noise than ordinary, due to the fact that the pads are drunk about the groove of the disk.

Carbon and ceramic

Provide good friction, less prone to heat generation. Carbon disks are designed for sports cars, so for ordinary cars are not quite suitable, since they need to warm up well for the correct work. Ceramic discs are made of carbon fiber, have a small weight and tolerate well tolerate. The disadvantage is a very high price.

But to increase the braking speed, it is necessary to increase the outer diameter of the disk. But it should be attentive: an increase in the size of the disk, as a rule, leads to an increase in the size of the wheel.

By the ratio of "price - efficiency", the best versions for tuning are ventilated brake discs, which, in addition to the blades of the air vents, have perforation, and irrigation. It is worth remembering that the tuning brake discs increase the wear of the brake pads as a result of increasing friction.

Caliper

The greater the pistons (4, 6, 8) in the caliper, the evenly distributed on the disk pressure during braking, thereby load on the disk and the pads is reduced, and vibration decreases. Such caliper unambiguously increase the efficiency of the brake system. Improved calipers, in addition to the lightweight mass (made of aluminum), have another plus - the ability to dispel heat better than cast-iron.

It is more convenient to acquire calipers with discs and brake pads. To date, calipers with four working cylinders are considered the best - two for each block. This leads to an instant triggering of the brakes when pressed on the pedal. It should be understood that the ventilated brake discs are wider than regular, and, as a result, the caliper will also be larger, which entails an increase in the diameter of the wheel, and sometimes its widths. Sometimes two calipers are installed for high-quality braking from two sides of the disk. Very often you have to change the calipers and fasteners, so it is more profitable to buy a ready-made kit for your car. And usually the pads and hoses are already included in it.

Hoses

This is a separate type of expenditure, because after replacing calipers and disks, it will be necessary to replace them. Improved brake hoses during operation do not expand on the pressure of the brake fluid, as rubber products, help to feel a pedal better, and they have a longer service life. To remove the inflatation of the brake hose, it is reinforced by a thin stainless wire, which has a special very dense weaving, which does not give the rubber hose to swell from the huge pressure generated when braking. Thanks to this brakes are made more predictable, efficiency increases significantly and the pedal reacts better.

Select the reinforced hose need exactly the same length as regular: long hose will increase braking, and a short can just snatch

Brake pads

They can be soft, medium and solid depending on the friction material. Here everyone decides for himself: if the car participates in competitions, albeit in amateur, it is necessary to use soft pads - they wear out faster, but it is better to brake. Solid brakes are worse, but they have longer service life, although they wear a disk.

Ideally, it is worth installing pads from the middle friction material: then it will be good to slow down, and the disc with the pads is not so quickly extended

Brake fluid

On the new system, it is necessary to use a special brake fluid with a high boiling point - the standard will not cope. Follow the overheating of the discs, as well as wear. This is especially important at the first stage of operation.

Naturally - you can not forget about the parking brake system. Instead of mechanical drive, use hydraulic. Manufacturers of tuning brake systems of high quality have their own production and their scientific laboratories. The leaders of tuning brake systems include companies such as Brembo, Delphi, Hamann, Nissin, Mugen and Stoptech and Endless.

Sergey Vasilkov, an exit territorial manager of the CIS countries, LLC Brembos Russia: "Almost everything that we do for the" civilian "cars was previously implemented and tested in the sports segment. To the issue of re-equipment of the brake system on the "civil" car must be approached with full responsibility. You must understand that all other car systems are designed for standard operating conditions, and the installation of "sports" brakes leads to critical loads - we do not see the point in re-equipment.

Moreover, the installation of the "sports" brakes on the cars of the urban operating cycle can be dangerous, since, on the one hand, it instills a sense of confidence to the driver and leads to an increase in the speed regime, on the other hand, the "sports" brakes stop the car faster than All cars in the stream, and this can lead to an accident.

Thus, if you are operating a car in the city and just want to be confident in the brakes, then the most reasonable to install discs with improved characteristics, the benefit from Brembo has such enough. These are painted discs, disks with Brembo Max notches, discs with Brembo Xtra perforation, floating and composite. And of course, to achieve the maximum effect, it is necessary to use Brembo pads and ensure that the calipers are in perfect condition. "

Monsters tuning prices varies from several thousand to several hundred thousand rubles for brake systems, depending on the car. But it should not be thought that the improvement of the brake system is to determine the super-cost event. So, Brembo has already brought to the Russian market a line of products for LADA cars, the prices for which are rather big, but quite adequate to the brand with the same name.

Among manufacturers, by the way, there are domestic brands working in this direction. These include, for example, High Performance Brakes or Carville Racing.

Maxim Atarov, Technical Manager Federal-Mogul Motorparts of Russia and CIS countries: "Ferodo has a rich experience in the development and production of friction mixtures for sports competitions. Until the mid-80s, Ferodo was the main supplier of friction components at the Formula 1 series competition. Until now, most sports teams in different types of competitions in auto and motor sports prefer Ferodo Racing products.

Based on the friction mixtures for racing, a separate series of Ferodo DS Performance disk brake pads was created, designed for tuning standard car models. These pads are in demand a certain category of clients who prefer a dynamic driving style. Naturally, in Russia, this product is also popular. It is quite clear that the operation of the machine with greater braking dynamics leads to more active wear of other components. "

What is the result?

If there is a desire to do motor sport even at the amateur level - here, as they say, God himself ordered. Without the enhanced braking system, the success on the track is not seen. If available is a powerful used car or there is a need to force the engine, then the full tuning of the brake system is an extremely desirable action. However, as in any case, you need to know the measure and understand what conditions and indicators this tuning is necessary. For "civilian" conditions, this is primarily safety, and therefore the experts do not get involved in powerful systems.

Well, as for proposals in the market, today they are enough to cover all price categories. So, with a competent approach, it is possible to noticeably increase the efficiency of one of the most important car systems, spending not the biggest money for it.

Improvement of the brake system of the car is the topic of today's article. As the ancient saying, the brakes came up with a coward, but sometimes to press the pedal decisively and in time, the short self-resting and driver's skill, fixed by the reliable operation of the car brake system. Many car owners independently engage in tuning their cars.

An increase in the power of the power unit leads to the fact that the braking becomes less efficient and can lead to irreparable consequences. The installation of a more powerful, disc braking system will help correct the situation.

Why are disc brakes instead of drum? The very first of their advantage in the design: Thanks to the speedy cooling, the disc brakes are rigorously and are subject to smaller overheating, even after a series of intense presses from high speed.

And the option using the front, brake disc and the upgraded brake brake brake on the rear wheels is also much more powerful by the standard installed manufacturer, drum brake system.

Of course, the power and energy intensity is good, but the expected effect may not happen from this. Why? When braking, the front and rear mechanisms of the car are in different conditions. The car "presses" the front axle, and the rear brake system remains without work.

To achieve optimal operation of the brake mechanisms, the wheels must be blocked absolutely synchronously, otherwise the loss of stability is inevitable and as a result of the skid.

In the equivalent blocking of the wheels, the brake force regulator is responsible. Its work is that it regulates the pressure in the brake cylinders of the unloaded axis and prevents its disruption and unwanted slip.

Improvement of the brake system of the car - when installing a more powerful brake system, it is necessary to reconfigure and regulator. That's where problems begin: the car slows down at no better than the standard drum system. The following occurs: the brake force regulator, as it should be evenly distributes the load on the front, weaker brakes, and tuned rear to the detriment of the efficiency of the latter.

The most rational solution in this case is the replacement of the front brakes more powerful. This will help make the system fully balanced. The result will delight you, and even the case is not in the distance of braking.

Disc brakes have a number of advantages in addition to high power. First, they are more accurate with minimal backlays and come into operation quickly.

Disc brakes are deprived of self-drawing in contrast to the drums that do not increase the driver of the driver, which leads to a sharp, difficult to control the braking. The first thing that we notice the set of disc brakes, not an increase in the slower speed, and the smoothness of braking is.

Improving the car brake system - get used to good, and in this case it is also safe.
