The caliper is equipped with a dust cover to prevent impurity particles from damaging the piston. In addition, an anti-rattle shim is also matched to fix the brake pads to reduce daily use noise.

[0004] The brake caliper is a clamping device with functions such as decelerating, stopping, or maintaining the stopped state of a moving wheel, and is usually used in a disc brake system. The disc brake consists of a brake oil pump, a brake disc connected to the wheel, and a brake caliper on the disc. When braking, high-pressure brake oil pushes the piston in the caliper, pressing the brake shoe against the brake disc to produce a braking effect. Air braking is a commonly used braking method for current automobiles, and appropriate brake calipers are also required for air braking.
