What should I do if the brake system fails? Top Ten Failure Analysis
The braking system is one of the most important systems for a car. It is an important system to protect pedestrians and yourself. What if the braking system fails?
1. Trouble phenomenon: step on the brake pedal, the pedal does not rise, there is no resistance;
Judging the reason: check whether the brake fluid is missing; whether the brake cylinder, pipeline and joints are leaking; whether the main cylinder and the parts of the cylinder are damaged;
2. Trouble phenomenon: Step on the brake pedal to the end, the braking effect is not good; continuous braking, the effect is not improved, and the pedal gradually rises;
Judging the reason: gas is mixed in the braking system;
3. Trouble phenomenon: Continuously step on the brakes, the pedal return is raised, and the braking effect is improved;
Judging the reason: the clearance between the friction lining and the brake drum is too large;
4. Trouble phenomenon: Continuously step on the brake, the pedal position rises, and there is a sense of sinking;
Determine the cause: oil leakage;
5. Trouble phenomenon: The pedal position is very low; if you step on it again, the position cannot be raised, and it feels hard;
Judge the reason: the master pump is blocked;
6. Trouble phenomenon: The pedal height is normal, not soft or sinking, but the braking effect is not good;
Judging the reason: the clearance between the friction lining and the brake drum is too large or there is oil stain;
7. Failure phenomenon: braking deviation;
Judging the reason: the car skews to the left, it means that the right wheel is not braking properly, and vice versa;
8. Trouble phenomenon: The brake drum (disk) heats up when the car travels for a certain mileage;
Judge the reason: check the brake master cylinder, brake cylinder or pipeline;
9. Trouble phenomenon: the free stroke of the brake pedal is too small;
Judgment reason: need to be adjusted;
10. Trouble phenomenon: the brake fluid level rises slowly;
Determine the reason: loosen the bleed screw and observe the return of the brake shoe. If the brake shoe returns, the oil pipe should be cleared; if the brake shoe does not return, the brake cylinder should be disassembled and checked.
