1. If the brake pedal is trampled several times in succession, the pedal does not rise and there is no resistance, you should first check whether the brake master cylinder is short of brake fluid.
2. If there is a shortage, add the same type of brake fluid and remove the air in the pipeline; if not, check whether each brake pipeline is leaking or damaged, and correct or replace it as appropriate.
3. Step on the brake pedal, if there is no linkage feeling, it may be that the connection between the pedal and the brake master cylinder is disengaged, and the connection structure should be checked and connected well.
4. If you step on the brake pedal, although you feel a certain resistance, but the position of the pedal cannot be maintained, it sinks significantly, and the master cylinder leaks or sprays liquid, which is mostly due to the rupture of the seal of the master cylinder. The brake master cylinder should be differentiated and the master cylinder seals replaced.
Extended information: If the brake pedal is trampled several times, the electric forklift cannot slow down and park. The solution is as follows: If the brake pedal is pressed several times in succession, the pedal will gradually rise, and the foot will not lift and continue to go down after rising. When you step on it, you can feel the elasticity of the pedal. You can release the pedal and stop for a moment before stepping on it. If it is still the same, there is air in the braking system and should be exhausted. The sequence of exhausting air should start from the master brake cylinder and then to each brake cylinder. The order of air discharge from each wheel cylinder should start from the wheel cylinder closest to the brake master cylinder, and discharge air one by one.
Exhaust method: 1 person is responsible for stepping on the brake pedal, and the other person is responsible for exhausting. Press the brake pedal to the end and then do not loosen it, then loosen the exhaust screw, wait until the brake fluid mixed with air is sprayed out and the pressure is reduced, then tighten the bleed screw and release the brake pedal. After the brake pedal is completely returned, depress the brake pedal again and continue to release the air. Repeat this several times to remove the air completely.
