Drum brakes are responsible for stopping the vehicle. Drum brakes are usually found on the rear wheels due to the need for a parking brake. Parking brakes are much easier to add to a drum brake than to a disc brake. Drum brakes contain different parts: brake shoes, which serve to press against the brake drum and create the friction necessary to stop the vehicle; a support plate that holds everything together and is fixed to the shaft; brake drum attached to the wheel; wheel or brake cylinder containing the pistons; return springs; and a self-adjusting system that will adjust the position of the pad when the brake is not inserted.
