Inside the caliper is a brake pad, a small block of friction material backed with a metal plate. When you step on your brake pedal, pistons inside the caliper cause it to apply pressure to the brake pad which squeezes the rotor, causing the car to slow or stop.
The caliper incorporates race technology into a body design with widespread adaptability. Radial mounting, two options for piston volume, and a rotor diameter ranging from 12.88 to 15.00 give this caliper the versatility necessary to suit all types of heavy weight braking requirements.
