Brake discs are friction parts of loaders. In addition to having the required strength and stiffness as components, they should also have the highest and stable friction coefficient possible, as well as appropriate wear resistance, heat resistance, heat dissipation, heat capacity, etc. As the friction part of the loader, the brake disc is prone to some failures, such as:

装载机制动摩擦衬片的损坏会导致金属衬片因摩擦而发出的尖叫声，并伴有过热现象。此时，我们应该更换刹车的摩擦片。

The damage of the loader brake friction lining will cause the squeal of the metal lining due to friction, accompanied by overheating. At this time, we should replace the friction lining of the brake.

制动钳上有一个固定的螺栓，螺丝松动将导致制动钳偏斜。此时，零件和制动盘会出现相互干扰的情况，也会引起异常的噪音。

There is a fixed bolt on the brake caliper. Loose screws will cause the brake caliper to deflect. At this time, the parts and the brake disc will interfere with each other, which will also cause abnormal noise.

低压软管零件老化、磨损，油管接头松动或此部分的密封件出现损坏。我们需要控制相关的部分，做好检查，拧紧接头或更换橡胶管、密封件和其他零件。

Low pressure hose parts are aging and worn, and the oil pipe connector is loose or the sealing element of this part is damaged. We need to control the relevant parts, check them, tighten the joints or replace the rubber pipes, seals and other parts.

制动钳的活塞上有一个密封圈。如果密封圈出现磨损的话，会导致制动液泄漏。这时，我们需要更换密封圈和防尘圈。

There is a sealing ring on the piston of the brake caliper. If the seal ring is worn, the brake fluid will leak. At this time, we need to replace the seal ring and dust ring.
