Question: 1 / 400

Which component is responsible for applying pressure to the brake pads in a disc brake system?

Brake shoe

Brake rotor

Brake caliper

The brake caliper is the component responsible for applying pressure to the brake pads in a disc brake system. It houses the brake pads and contains one or more pistons that are activated by hydraulic pressure. When the driver depresses the brake pedal, the master cylinder generates hydraulic pressure that travels through the brake lines to the caliper. The fluid forces the pistons within the caliper to push the brake pads against the spinning brake rotor. This action slows down the vehicle by creating friction between the pads and the rotor.

Understanding the function of the brake caliper is crucial for anyone studying automotive braking systems. It plays a direct role in the braking process by ensuring that the necessary force is applied to produce effective stopping power. This mechanical interaction is essential for the safety and performance of the vehicle's braking system.
