How to determine if the brake master cylinder is broken? Symptoms of a broken brake master cylinder

The brake master cylinder, as the main component of the vehicle's braking system, is undoubtedly crucial, but its damage rate is quite high and can directly affect the braking effect. The manufacturer of the brake master cylinder, of course, many friends still don't know if there is really a problem with the brake master cylinder. How can we determine if the brake master cylinder is broken, what are the symptoms of a broken brake master cylinder, and what should we do if it is really broken.

Symptoms of brake master cylinder damage

Brake is too soft:

When we step on the brake, if we feel that the texture of the brake is noticeably soft and the stability of continuous braking decreases, it may be due to poor sealing of the master cylinder and cylinder pistons, or a rupture in the brake pipeline, leading to oil leakage. At this point, we need to observe if there are any traces of brake fluid.

Sudden brake failure:

When a car is braking, if it suddenly malfunctions for a moment, it is necessary to observe whether the brake fluid is depleted, and then check whether there are brake marks on the master cylinder, cylinder, and oil pipe. If there is any, it means that the brake master cylinder or cylinder has serious oil leakage and must be repaired in a timely manner. It should be noted that the consequences of brake failure are very dangerous.

Brake deviation:

If you feel that the braking direction is off track, it is likely due to the expansion of one piston in the master cylinder, or it may be caused by uneven brake wear. But this phenomenon must be resolved in a timely manner, because it is difficult to control the direction when running off track, especially for cars without ABS braking and anti lock braking systems, which pose certain dangers.

Brake pedal not returning or returning slowly:

If the brake pedal does not rise or resist after being pressed, it is what we call the brake non return phenomenon. At this point, we need to check if there is any damage to the components of the master cylinder and cylinder. Secondly, this phenomenon may also be caused by a lack of brake fluid or oil leakage.

Overall, no matter what symptoms occur, there are always certain safety hazards, and there are still many factors that can cause problems to arise. It will definitely be quite difficult to solve the problem by doing it yourself, and it will only be a temporary solution without addressing the root cause. So when these symptoms appear, you should go to the corresponding 4S shop or auto repair shop for inspection and repair as soon as possible.
