Those motorists who have encountered the problem of a failed brake pedal know firsthand how extreme this situation can be. You can talk about what consequences an inoperative brake system can lead to infinity, so in order not to get into an emergency, you should carefully look at the technical condition of this system and regularly do diagnostics.
In this article, we will consider the reasons that affect the failure of the brake pedal. We will also learn how to act in such situations and what details should be paid attention to.
Why does the brake pedal fail, and what is the way out of this situation?
The most common case of such "surprises" lies in the depressurization of the brake system. There are several reasons for this: a low liquid level, and the appearance of gaps between pads and discs, and even the presence of air in the system. All of them lead to emergency situations. And in order to resume the functions of the pedal, you should add brake fluid in the first case, and in the rest - pump the system and adjust the pads.
Sometimes it happens that after installing a new disc on domestic cars, including the VAZ 2110, the brake pedal fails. But before that, it knocks for a long time, and when braking, you will feel as if speed decreases in jerks. In this case, carefully read the instructions that came with the disk manufacturer. If it says that there may be problems with the brake system in the first 300-500 kilometers, this means that the disc should be run in. If the problem persists after running in, you should immediately send the car for diagnostics and find out the exact cause of the breakdowns. At the service station, it may turn out that the malfunctions can be hidden in the ABS system or in a deformed disk.
If you notice how the brake pedal fell to the floor, and then after 5-10 seconds it slowly returns to its place, this is also a serious sign. In this case, check the condition of the brake master cylinder. It is best to diagnose with a return spring and after that check the brake fluid level. If its level has not decreased, a cylinder replacement is inevitable. Otherwise, the pedal will simply jam and then the car will roll on its own. If you notice that the brake pedal is hissing, this indicates a faulty vacuum pump. In this case, it is best to contact a service center.
So, we examined all the main reasons why a situation may arise when the brake pedal has failed. Now we know all possible ways out of situations. And finally, advice to all motorists (it doesn’t matter whether you have already encountered this problem or not) - always monitor the brake fluid level and add it regularly, and after this period, drain it and fill in a new one.
