As the main part of the brake system of the whole vehicle, the brake master cylinder is of course very important, but the damage rate of this part is quite high, and it will directly affect the braking effect. Of course, many friends still don't know if there is a problem with the brake master cylinder. So how to determine that the brake master cylinder is broken, and what is the performance of the brake master cylinder, and what should be done if it is really broken.
Brake master cylinderdamagePerformance
Brake is soft:
When we step on the brake, if we feel that the texture of the brake is significantly softer and the stability of continuously stepping on the brake is reduced, it may be due to poor sealing of the master cylinder and wheel cylinder piston, or a certain brake pipeline. There was a rupture in one place, causing an oil leak.At this time we need to observe whether there isBrake FluidTraces of it.
The brake suddenly fails:
When the car is braking, if it feels that it suddenly fails for a moment, you need to observe itBrake fluidWhether there is a loss, then check the master cylinder, sub-cylinder and oil pipe for signs of brakes. If there is, it means that the brake master cylinder or the sub-cylinder has leaked very seriously, and it must be repaired in time. It is necessary to know that the consequences of brake failure are very dangerous.
Brake deviation:
If you feel that the brake direction is off, it may be due to the expansion of a piston of the master cylinder, of course, it may also be caused by uneven brake wear. However, this phenomenon must be solved in time, because the direction of the deviation is difficult to control, especially for cars without ABS brake anti-lock system, there is a certain degree of danger.
The brake pedal does not return or returns slowly:
If after stepping on the brake pedal, the pedal neither rises nor resists, it is what we call the brake non-return phenomenon. At this time, we need to check whether the parts of the master cylinder and the sub-cylinder are damaged. Secondly, this phenomenon may be caused by lack of brake fluid or oil leakage.
In general, no matter what symptoms appear, there are certain safety risks, and there are many factors that cause problems. It must be quite difficult to solve it with your own hands-on inspection, and it will be a symptom rather than a permanent cure at that time. So when these symptoms appear, you should go to the corresponding 4s shop or auto repair shop for inspection and maintenance as soon as possible.
