Why brake the brake when braking?

In absolutely any car, regardless ofbrand and year of release, the key element responsible for safety are the brakes. If the brake pedal beats during braking, this is not a good sign. If such effects appear, it may be necessary to completely diagnose the vehicle. Let's look at the typical reasons for this phenomenon.

Direct causes

When when the brake pedal is pressed, the heartbeat is felt, then an urgent and complete diagnosis is necessary.damages the brake pedal when braking To do this, you should turn to a qualitativecar service, where qualified specialists work. However, it is possible to identify the reasons why the pedal beats when braking, independently. This method is suitable for experienced motorists.

How does the effect manifest?

Often the beats appear at high speeds. So, there is a pattern - higher speed - more vibration. Often they are felt not only on the brake pedal, but also on the body of the car, as well as on the steering wheel. It is very difficult not to notice this beating. If the vibrations are felt more on the body than on the elements of the system, then the brakes in this case are not the cause. But carefully check them all the same recommended.

Brake discs

Among the most common and popular reasons can be identified broken and damaged discs. They, in turn, can fail due to various damages or deformations.when braking, it breaks the brake pedal Disks break due to critical differencestemperatures. When braking, the element instantly warms up, and then it also drastically cools. It is because of these temperature fluctuations that various curvatures occur. If the brake pedal beats during braking, then carefully check the elements for breakage, cracks, deformations. If any defects are detected, the damaged part should be replaced immediately. To check where exactly the defective disk is installed, use a handbrake. If in this case there is no vibration, then the culprit is in front.

Also, sometimes vibrations may appear due tocorrosion, but wear on the working surface can be normal. In this case, it is recommended to run the discs. This should be done by an experienced turner. However, there are technologies of grooving directly on the machine, without removing the discs. This procedure is much cheaper. Also, you need to make sure that the disks are properly mounted. If the installation on the parking surface is poor, the braking will be accompanied by a beating effect.

New disks and general system malfunctions

But even after installing the best quality discsProblems can still be felt. Often, the brake pedal brakes when braking on the first hundred kilometers of the car. The reason is a sharp decrease or deterioration in the performance characteristics of the entire system as a whole.

To solve this trouble, run-in is useddisks. However, even if this did not have its effect, thorough diagnosis is recommended. Special equipment will help to pinpoint the causes of heartbeats.

Pads

Among the malfunctions of the brake system in the car can be pads.when braking, the brake pedal and the steering wheel This problem is easy to cure. It is enough simple replacement and beating will stop. Often, the brake pedal brakes when braking because of the so-called "sticking" of the rear pads. If you press the pedal too hard and too fast when driving at high speed, inexpensive items can be painted. In this mode, they wear out quickly. The output is simple - replacement.

Rear Drum

This fourth reason, because of which the pedal can not work in normal mode.hits the brake pedal while braking the gazelleThis often happens on the "GAZel". There, the rear brake drum is deformed, and therefore the brake pedal is depressed when braking. "GAZelle" rear is equipped with a drum brake. If it is in a neglected state, then it is natural that there are vibrations.

Brake Cylinders

This is the last of the most common reasonsthe appearance of beats and vibrations on the pedal. Often cases, when both the front and rear cylinders of the brake system are sour. This contributes to various malfunctions.

To defeat this problem, you can do withoutreplacements - the problem is solved with the help of WD-40. It is enough to sprinkle this miracle tool, and it is possible that the brakes will start working as needed and conceived by engineers.

Indirect malfunctions

If after checking the sample and popularfaults still brake the brake pedal when braking, then the problems should be sought in other most unexpected places. To other malfunctions, which can cause the effect of vibrations or beats, it is possible to include the stupile bearings, which are very worn out during operation. The situation can be corrected by their replacement. In addition, due to operation, the levers on the front wheels wear out.

Also, vibrations can appear as a result of unbalanced wheels.why the brake pedal brakes when braking In this case, the pedal beats hard, but the main thuds are given all the same to the body. Solving this issue is not difficult - in the simplest case balancing will help. In the worst case, the wheels will have to be replaced.

If you checked everything, but could notFind out why the pedal beats when braking, then check the tightening of nuts, bolts and other fasteners. Not fully tightened fasteners can be the culprit for the appearance of backlash. At high speeds, this can cause significant run out, and in such cases the brake is checked.

When braking, the brake pedal and the steering wheel

Sometimes vibration on the brake pedal is added to the vibration on the steering wheel. There are many reasons for this effect. This is imbalance, worn brake pads, steering rods, cardan gear.

Even if it seems that the wheels are excellentbalanced, this is not yet a guarantee that everything is really good. To find out if this is the case, you need a special stand. Balancing is recommended for all wheels at once.

A common problem with domestic cars andforeign cars - wear of the front shoes. Because of this, the wheel rushes. To carry out the diagnosis, the machine is installed on a pit and inspects the discs and pads. If there is a serious wear, then only a replacement, if the wear is small, then you need to look for the real reason. Often when braking, the brake pedal beats (VAZ-2110 is no exception), and also the steering wheel. Experienced car owners recommend checking the rear pads and the entire system if the vibrations are felt on the pedal, and if on the handlebar - then look at the brakes in front.

Steering links

The steering wheel beats because of the wear of the tips on the steeringtraction. It is necessary to look for a possible shack in these mechanisms. If there is no free running during the jerking, then the traction is all right. If the link is loose, you should replace it, but this operation implies the subsequent procedure of the collapse-convergence.

Cardan transmission

It would seem, and here it is, however experiencedauto mechanics argue that the causes of vibration on the pedals and steering wheel can hide in this very transmission. When worn crossings can be felt and vibration, and heartbeat. Check the condition of the frogs and replace the worn out assembly if necessary. Such problems are often observed on "GAZel".

Ball bearings

Experienced motorists recommend to thoroughly check the entire chassis.when braking, the brake pedal beats VAZ 2110 The reason can be hidden anywhere. So, not infrequent cases, when the brake pedal brakes during braking (VAZ-2114 is no exception) due to a faulty or worn ball bearing. This is the first thing to check.

For inspection, the machine is lifted with a jack, andThe ball joint is installed in such a way that the wheel is suspended in the air. Then, with the palm of one hand, take the wheel by the upper part, and the second hand by the lower part. Hands need to shake the wheel. If the reel is and is felt, then the ball joint must be changed. This should eliminate vibrations and knocking.

Human factor

This point can not be ruled out either. Sometimes it happens, but the situations are very different.hits the brake pedal when braking VAZ 2114 If you change the wheel, you (or the master) stronglythey hurried to finish the work, they could not tighten the fixing bolts until the end. Such inattention can lead not only to vibrations and beating on the pedals. So you can lose the wheel. Apparently, there are a lot of reasons. They are all different. All of them cause the same effect. You should carefully monitor the condition of the car, if necessary, replace worn parts and components in time. Also, you should listen to the recommendations of car manufacturers.

So, we found out why the brake pedal brakes when braking.
