Before using the brake, check whether each part is normal and often encounter an inconvenient operation.
1. The brake lubricating oil is insufficient, resulting in increased the friction of the brake, and the brake is not sensitive.
2. the oil returning valve is poorly sealed, and the oil valve is broken, causing the elasticity of the rotation support to decrease, causing unfollow.
3. brake points pump skin bowl aging, swelling, piston card, causing unflexible braking effect.
4. brake shoe, the brake gap is too large, causing the operation.
5. The braking effect caused by braking drum is unambiguous.
6. The brake hydraulic system enters the air, causing insufficient hydraulic system.
7. The braking effect caused by brake wear is not sensitive.
