General description The Floating Brake Caliper Rear is designed to effectively clamp onto the wheel’s rotor, stopping the wheel from turning when the brakes are applied. Inside each caliper, a pair of metal plates known as brake pads work together to slow down the vehicle by pressing against the brake rotor when brake fluid creates pressure on the pistons.
