The process added hydraulic pressure to make it more practical to stop larger and faster vehicles. Many of these systems use levers to apply and retract the brake pads.ĭrivers of cars with early disc brake systems had to provide the muscle to apply the brakes. Think about how braking systems work on bicycles. The original caliper design used mechanical cables to squeeze the brake pads into the rotor. These hoses and lines retain and circulate the brake fluid and pressure to and from the brake master cylinder. The top of the caliper is attached to the brake master cylinder with flexible brake hoses and steel lines. This seal keeps dirt and debris from damaging the piston and stops the brake (hydraulic) fluid from leaking. When the brake pedal is released, the pistons and the pads retract into the caliper allowing the rotor to spin freely.Ī flexible seal surrounds each caliper and piston. The rotor turns and slows down the wheels and tires. The brake pads sit against the pistons, with the brake pad friction material facing the rotor.Ĭalipers do not move so when the brake pedal is applied, the pistons and the brake pads push from the caliper to squeeze against the rotor. It is bolted to the suspension and has a slot in the middle for the brake rotor to turn.Īlong the insides of the caliper are one or more pistons. They use hydraulic pressure to squeeze the brake pads against the brake rotor, applying friction that restricts the movement of the rotor and slows down the vehicle.Ī caliper looks like a giant kidney. Brake Calipers Purposeīrake calipers house the brake pads. These components are the brake pads, the brake caliper, and the brake rotor or disc. Modern disc brake systems work with the coordinated effort of three primary components.
