A drum brake is a system consisting of a set of brake shoes that are forced on the outer drum-shaped cover to stop the vehicle. It is a cost-effective type of brake system used in automobiles. A drum brake has two main parts, such as the lining and the shoes. The lining is made of a material that can create friction, such as asbestos, and the shoes are metal plates that squeeze against the lining. Moreover, the drum brake system has existed for a long time and has become an integrated part of the automobile industry. Drum brakes are mostly used in heavy-duty and medium-duty commercial vehicles.
