brake drum
A brake drum is an important part of a vehicle’s breaking system, which slows or stops motion by absorbing kinetic energy and transforming it into heat. Basically, its job is to provide friction in tandem with the brake shoes and slow down the rotation of your wheels. The brake drum itself is usually made from hardened cast iron or similar tough and heat-resistant material. It is a cylindrical shaped drum with its surface being flat which contacts with the brake shoes. This design ensures a balanced grip and an optimised brake performance. Applications: Brake drums are mostly used in older cars, commercial trucks and some kind of trailers. These pumps are suitable for various automotive applications because of their simple and dependable structure.
