The function of a brake caliper is to ensure firm and responsive braking, thereby shortening the vehicle's stopping distance, enhancing overall braking performance, and safeguarding driving safety. The caliper is equipped with dust boots to prevent particulate contaminants from damaging the piston; additionally, it features anti-rattle clips that securely anchor the brake pads, effectively reducing noise during daily operation.

 

A brake caliper is a clamp-like mechanism designed to decelerate a moving wheel, bring it to a complete stop, or maintain it in a stationary position; it is typically utilized within disc brake systems. A disc brake assembly consists of a brake master cylinder, a brake disc (rotor) attached to the wheel, and a brake caliper mounted over the disc. When the brakes are applied, high-pressure brake fluid drives the piston within the caliper, pressing the brake pads against the brake disc to generate the necessary braking force.
