The caliper is one part of the brake system.
A caliper is a measuring tool that measures either the inside or outside diameter of something. Disc brakes on a car use a caliper to push the brake pads against the rotor to stop the car.
When disc brakes are applied, a caliper squeezes the brake pads against the disc and the wheel slows. When drum brakes are applied, curved shoes located inside the drum are pushed outwards, rubbing against the inside of the drum and slowing the wheel.
