[0002] A loader is an earthwork construction machine widely used in construction projects such as highways, railways, buildings, hydropower, ports, mines, etc. It is mainly used for shoveling loose materials such as soil, sand and gravel, lime, coal, etc., and can also perform light shoveling operations on ores, hard soil, etc. It mainly consists of four major components: an engine, a torque converter, a gearbox, and front and rear drive axles. A brake caliper is a type of brake used in the braking system of a loader;

[0003] Most of the existing brake calipers are screwed onto the axle of the loader through high-strength screws, and most of the brake pistons of the brake calipers can only be taken out inward from the direction of the brake pads. Therefore, when repairing the brake caliper, the high-strength screws must be unscrewed, and then the brake caliper must be disassembled for repair. There are many parts to be disassembled and assembled, which is time-consuming and laborious. In addition, the operating space for disassembly and assembly from the inside is small, and the disassembly and assembly are relatively difficult. In addition, the brake pistons in the brake calipers are frequently used on the loader and need to be regularly maintained and repaired, which increases the workload and makes it impossible to complete the efficient repair operation of the brake pistons, affecting the overall efficiency.
