DRUM BRAKES
A drum brakes is a brakes that uses friction caused by a set of shoes or pad that press against a rotating drum shaped called a brakes drum. When the brakes are applied, brakes is forced to pump under pressure from the master cylinder into the wheel cylinder. Which in trun the brake shoes into contact with machined surface on the inside of the drum. This rubbing action reduces the rotation of the brake drum, which is coupled to the wheel. Hence the speed of the wheel is reduced. When the pressure is released, return spring pull the shoes back to their rest position.
Drum brakes works on the same principle as disc brakes. Shoes press against a spinning surface. In the system surface is called drum. Drum brakes have more parts than disc brakes and are harder to service, but they are less expensive to manufacture and they easily incorporate an emergency brake mechanism.
