Before using the brake, check whether all parts are normal. Zhongyuan Brake analyzed the following fatal problems that directly lead to the inconvenience of brake operation:
1. The brake lubricating oil is insufficient, causing the brake friction to increase and the brake to be insensitive.
2. The oil return valve is not well sealed, and the spring of the oil outlet valve is broken, resulting in a decrease in the elasticity of the slewing bearing and inflexibility.
3. The brake cylinder cup is aging, swollen, and the piston is stuck, resulting in inflexible braking effect.
4. Brake shoes, the brake gap is too large, resulting in insensitive operation.
5. The braking effect caused by the brake drum is not sensitive.
6. The hydraulic system of the brake enters the air, resulting in insufficient strength of the hydraulic system.
7. The braking effect caused by brake wear is not sensitive.
