This is ironic, because the spot-type disc brake is an American invention. In 1898, Elmer Ambrose Sperry of Cleveland designed an electric car having front-wheel disc brakes. He made a large disc integral with the hub on each wheel.
Brake calipers are essential to your car's ability to stop and are arguably one of the most important automobile brake parts. Most cars today have disc brakes, at least for the front wheels, anyway. But a lot of cars and trucks are now using disc brakes in the rear, too. In a disc-braking system the car's wheels are attached to metal discs, or rotors, that spin along with the wheels. The job of the caliper is to slow the car's wheels by creating friction with the rotors.
