The car braking system is one of the key components of vehicle safety, and the brake caliper is one of the crucial components. This article will introduce the function and structure of brake caliper in detail to help readers better understand the vehicle braking system.

function of brake caliper

The brake caliper is one of the key components of the braking system. It mainly completes the following functions:

Conversion of braking force: brake caliper is the "clip" in the braking system, which converts braking force by clamping the brake disc to slow down or stop the vehicle.

Distribution of braking force: brake caliper can evenly distribute braking force to each brake disc to ensure that the vehicle can brake stably and balancedly.

Brake system control: Some vehicles are equipped with an electronic brake system (EPS), and the brake caliper can also be controlled through this system to provide more precise and faster braking effects.

Structure of brake caliper

Brake caliper usually consists of the following main components:

Caliper housing: The brake caliper's housing is a solid metal shell that is fixed to the vehicle's suspension system.

Brake piston: One or more pistons are installed inside the brake caliper, which compresses the brake pads to clamp the brake disc. Pistons are usually made of rust-resistant materials to ensure proper operation.

Brake pads: Brake pads located inside the brake caliper that come into contact with the brake disc and create friction to slow down the vehicle.

Brake fluid pipe: Responsible for delivering brake fluid from the master cylinder to the brake caliper to push the brake piston to exert force.

Piston seal: A seal is installed between the brake caliper's piston and the brake caliper housing to prevent brake fluid leakage and keep the brake system in good working condition.
