Many drivers in the car process often encounter some problems on the road safety, some drivers are sensitive to the timely detection of problems, and some drivers with less experience in the car, the knowledge is not hot, car brakes is the best example. In the process of using the car brake abnormal sound, brake soft and hard and other small problems, will affect the safety of the car, small problem is a false alarm, if the big problem can be regretted. The following masters introduce a few of the car brake failure phenomenon.

1. Brake Abnormal sound

　　

Brake abnormal sound is a common brake failure, often encountered in the driving. Fault phenomenon for the brakes on the brakes will be a sharp harsh metal friction, this situation is more than the brake pads have hard material impurities, resulting in hard grinding with the brake disc caused. The rear axle of the drum brake can be a result of improper adjustment of the brake clearance, or the delay of the brake shoe return position. There is a long time to lift the car after letting go BLL abnormal sound, most of the brake pads/brake shoe back position problem.

2. Tremble when stepping on the brakes

　　

This situation is not uncommon, mostly because of excessive wear on the brake pads/brake Discs, the surface flatness of the brake disc has been misaligned to a certain extent, the brakes on the constant friction caused by the feeling of trembling, brake pedal bounce, this situation should be timely to 4s shop or repair workshop (if the brake disc problem is generally directly replaced).

3. The brakes do not return to the position

Brakes do not return to the feeling very close to the brake soft, when the brake pedal, pedal resistance is not rebound, this situation when the owner should be vigilant, first look at the brake oil pot brake oil, then immediately drive to the repair shop. This is likely to be the presence of leaks or air in the brake circuit.

4. The brake becomes soft

　　

Brake soft is the brake when the brakes are very soft, especially large, this situation is due to the failure of the caliper, such as brake pads, brake disc wear caused pedal travel longer, brake oil in excess of water, brake circuit air and so on. When this occurs, the pedal can be checked to see if the pedal is still soft when braking several feet in a row.

5. Brake Hardening

The problem of hard braking is relatively simple, because the brakes become more rigid brake power reduction, and will not affect the effect of the brakes. Self-test method is also very simple, in static when a few feet brake to harden the brakes, then the car, if the car brake immediately after the brakes to prove that there is no problem, on the contrary, you should enter the shop to check.

6. Brake deviation

　　

On the brakes, the steering wheel will be deflected towards one side of the trend, we commonly known as this is called "eccentric brake." The main reason for the failure is that the brake is caused by uneven force on the left and right side of the pump. In the normal driving process of the brake disc rotation speed quickly, the sub-pump action is not evenly caused by the trend of this deflection, this situation will also lead to the phenomenon of friction brake disc, so it is best to detect this phenomenon in time (change the brake disc indicator).
