Brake caliper and loader

The utility model provides a brake caliper and loader. Brake caliper, including the piston and the pincers body, the piston set up in clamp internally, brake caliper still includes: the dust ring, the cover is located on the surface of piston, the dust ring includes first end and second end, first end by the internal surface of the pincers body inserts clamp internally, second end by the surface of piston inserts in the piston. The utility model discloses an among the brake caliper, it is internal that the first end of dust ring inserts pincers, in second end inserts the piston, can prevent effectively that impurity from getting into the clearance between the pincers body and the piston in, effectively avoid the piston jamming that rusts, and then make the piston return good, guarantee good braking effect. 本实用新型提供了种制动卡钳和装载机。制动卡钳，包括活塞及钳体，所述活塞设置于所述钳体内，所述制动卡钳还包括：防尘圈，套设于所述活塞的外表面上，所述防尘圈包括第端和第二端；所述第端由所述钳体的内表面插入所述钳体内，所述第二端由所述活塞的外表面插入所述活塞内。本实用新型的制动卡钳中，防尘圈的第端插入钳体内，第二端插入活塞内，可以有效防止杂质进入钳体和活塞之间的间隙内，有效避免活塞生锈卡滞，进而使活塞回位良好，保证
