Brake failure is mostly caused by wear, leakage or insufficient air pressure, so regular inspection and maintenance are needed to prevent it.

When I stepped on the brakes, I found that the brakes were useless, the speed of the car did not decrease at all, and the brake failure was very dangerous. What is the cause of the brake failure? How should we avoid it? Many times, brake failure is actually a precursor.

First, if the brake suddenly hardens, it is likely that the vacuum booster pump fails to work, so it is necessary to check whether the vacuum booster pump is damaged or falls off.

Second, the brake suddenly becomes soft and treads like cotton. This situation may be caused by brake oil leakage due to brake oil pipe damage.

Third, when stepping on the brake, the pedal is soft and hard, and the strength is big and small. It may be that the brake oil enters water or air, and the brake oil should be removed or replaced in time. It may also be that the vacuum booster pump is aging or damaged.

Fourth, the steering wheel wobbles when you step on the brakes. This situation may be uneven grinding and excessive runout, so it is necessary to replace the brake disc in time.

Fifth, when you step on the brakes, the steering wheel deviates. This is because the brakes on one side are not working or the braking force is getting smaller. Check the brake calipers in time.

If you think it’s useful, remember to like it and pay attention to it. Braking is no small matter. If these things happen to your car, you must check it in time and don’t take any chances.
