Riding on the vehicle is always a certain risk, the level of which has no only human factor, but also the health and proper functioning of the main systems. In this case, the most important node are brakes. It is the effectiveness of their work that predetermines the overall safety of movement. If the driver in braking notices the beat of the brake pedal, you should not leave it without attention. Ignoring such symptoms may well lead to a complete or partial damage to the brake system.

Brake system, brake system device

The main purpose of the brake system is to manage a change in vehicle speed, its stop and holding in place for a long time by using the brake force between the road and the wheel.

Brake force can create a wheelchair brake mechanism, a car engine, an electric or hydraulic retarder brake in the transmission.

To implement the specified functions on the vehicle, such types of brake systems are mounted - the main one (that is, the working), reserve and parking (handbrake).

Working (main) brake system provides a vehicle stopping and a controlled reduction of speed.

A spare brake system is applied when the work system fails or fails. It functions similarly to the main system. The spare brake system is implemented as a special autonomous system or part of the main brake system (brake drive circuit).

The main purpose of the parking brake system is to hold the vehicle in place for a long time.

The brake system is a very important means of ensuring the safety of the vehicle. In cargo and passenger cars, a variety of systems and devices are used, which make the brake system more efficiently, and also stable when braking - an emergency braking amplifier, anti-lock system, brake amplifier, and so on.

Beats the brake pedal when braking, what kind of danger causes this problem

Brake pedal beating - presence of outsiders and vibrations when braking. Usually, the higher when braking the speed, the stronger the beating.

In addition, it is possible that during braking at a speed of 120-140, the beating will give not only on the pedal, as well as on the steering rail and body. As it was already above, it is not stated, it is impossible to leave this problem, since as a result of inaction, it may refuse the brake system.

Causes of Bilation, Curves or Damaged Brake Discs, Driver Actions

The first and most common cause of the beat of the brake pedal, which, as a rule, is called a hundred, is damage to the brake disc curvature.

Often, it is formed as a result of a sharp temperature difference - first the brake disc is heated, after which it is sharply cooled (or vice versa). Because of this, the deformation of the brake disc occurs, and the brake pedal when braking begins to beat.

Exit from the situation is one - replacement of brake discs on both wheels. There were only one brake disc, as a result of various brake disc wear, braking efficiency can be worse. However, in some cases, the beating after replacement remains. As a rule, after a small run-in, this symptom leaves, but if not, the reasons are two - the detail is poor or there is another malfunction.

Pads Brake Front, in what condition they are

The front brake pads are not rarely the cause of the brake pedal, and more precisely, their damage, abrasion or wear. To diagnose breakage, you should check the quality of the surface and the thickness of the products. If necessary, replace the front brake pads.

Rear brake pads in which state they are

Usually, drum brakes are mounted on the rear wheels of Vazovsky cars, which have one disadvantage - the high risk of moisture accumulation, dust and dirt inside the drum.

As a consequence, the brake pads are able to shindle, collapse or subjected to rapid wear. As a result, the brake pedal beating begins.

The output from the situation is the complete replacement of the brake pads on both wheels (on one axis).

Rear brake drums in what condition they are

The cause of the beyon is able to become not only the rear brake pads, but also the brake drum itself. It can be twisted or deformed during operation. The touch of the pad to the deformed drum will inevitably lead to vibrations that will be tangible in the brake pedal.

Front and rear brake cylinders

Their incorrect work or a malfunction is also one of the probable causes of beating.

You can try to solve the problem with the help of rescue WD-40, however, if the tool does not help, without replacing the cylinder can not do.

Other reasons that rarely meet

In addition to the above, it is possible to distinguish several more reasons why the brake pedal can beat the brake pedal:

1. Deformation or damage to the levers of the front wheel - "Sabli".
2. Wear hub bearings.
   
3. Broach bolts. At the first symptoms of beating, make sure that the screws are broken. Such a reason is very banal, however, as a result of poor-quality broach, the backlash and braking pedal beating may form.
4. Wheel balancing problem. It is very easy to recognize - vibrations will be tangible not only in the brake pedal, but also on the entire body of the vehicle. Ignore this problem is dangerous to health and life.

Tips of professionals

It is not necessary to count on the fact that the problem is settled by itself, as it is possible that it will lead to serious trouble on the road. To avoid problems with the brake system, the level of brake fluid should be regularly replenished, systematically diagnose the brake system about the absence of leaks and the correctness of the work, as well as to care for the car and not bring the vehicle to the started state.
