Therefore, the brake drum plays an indispensable role in the brake system. If the wheel pump is broken, it will have a great impact. Although there are no lights, we can judge whether there is damage through the feedback effect of braking. So where is the breakdown of the brake cylinder.

The performance of the brake cylinder is broken

Soft brake:

When we step on the brake, if we feel that the texture of the brake is obviously soft, and the stability of continuously stepping on the brake decreases, it may be that the piston seal of the master cylinder and the slave cylinder is poor, or some part of the brake pipeline breaks, causing oil leakage. At this time, we need to observe whether there are traces of brake oil.

Sudden brake failure:

When the car is braking, if you feel that there is a sudden failure in a moment, you need to observe whether there is a loss of brake fluid, and then check whether the brake master cylinder, wheel cylinder and oil pipe have brake traces. If there is, it means that the brake wheel cylinder or master cylinder has leaked oil very seriously. It must be repaired in time. It is very dangerous to know the consequences of brake failure.

Brake deviation:

If you feel that the brake direction deviates, it is likely that the brake cylinder is rusty, or one of the pistons inside is expanding. Of course, it may also be caused by uneven brake wear. However, this phenomenon must be solved in time, because it is difficult to control the direction of deviation, especially for vehicles without ABS, there are certain risks.

The brake pedal does not return or returns slowly:

If the pedal does not rise and there is no resistance after stepping on the brake pedal, it is the phenomenon that the brake does not return. At this time, we need to check whether the brake master cylinder and wheel cylinder parts are damaged. Secondly, this phenomenon may be caused by the loss of brake fluid or oil leakage.

Generally speaking, there are many kinds of damage to the brake wheel cylinder, but no matter what the situation is, it will endanger the driving safety, so it is necessary to check and deal with it in 4S as soon as possible. Of course, if it's too expensive, we can go to the garage to repair it. But it's not recommended to do it yourself, because if you don't handle such a complicated problem properly, it's a case of "treating the symptoms rather than the root causes".
