Brake system failure and exclusion

Braking failure

Continuously step on the brake pedal, the pedal is not rising, and it feels no resistance. You should check if the main cylinder is lack, and then check the master cylinder and the execution pump. If there is a leakage, the seal should be replaced; If there is no oilproof oil, if there is a leakage, it should be repaired or replaced; if no oil should check, there is no disengagement of each mechanical connection. If the above situation is good, the state of the inspection of the main cylinder kitwear and the piston should be decomposed, and it is necessary to repair or replace if necessary.

Brake

1. When the brake pedal is stepped on, the position is very low, and the pedal gradually increases, but it feels weak, and the braking effect is not good. This shows that there is air in the brake system to exclude;

2. When the pin is braked, the pedal position gradually increases, and the brake effect is better. This shows that the pedal free trip is too large, the friction sheet and the brake disc gap are too large or the friction plate is severely worn. First check the adjustment pedal free travel, and then replace the friction sheet assembly;

3. If continuous stepping on the brake pedal, the pedal position can rise, but continue to step on the sinking feel, this shows that there is an oil leakage at the brake system or the main cylinder valve is not strict, and the inspection and repair should be carried out;

4. When the pedal is pressed, the pedal position is very low, then continuously step on the pedal, the pedal position can not rise, generally into the oil joys, and should be checked;

5. When the brake pedal is stepped on, the pedal is highly required, and it is not soft and weak, but the brake effect is not good, then the wheel brake fault, such as frictional hardening, oil, brake disc deformation, etc. Maintenance wheel brake;

6. The quality of the brake fluid is not good, the tubing is depressed, blockaged or leaks, and performs corresponding maintenance.

ABS system failure

1. Whether the parking brake is completely released, whether the brake fluid is compliant;

2. ABS computer wire plug, whether the connection is good, whether the sensor and wire are damaged;

3. Relay and the inner are intact;

4. Whether the battery capacity and the voltage meet the regulations;

5.Abs computer, hydraulic control device grounding wire is connected;

6. Check whether the cable of the electrical component such as a wheelbench sensor, an electromagnetic valve body, and an electric pump are connected to whether there is damage to the wire.
