Drum brake (upper right) with the drum removed (lower left, inside facing up), on the front of a Ford Falcon Sprint A rear drum brake on a Kawasaki W800 motorcycle. A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating bowl-shaped part called a brake drum.
A wheel cylinder is a component of a hydraulic drum brake system. [1] It is located in each wheel and is usually positioned at the top of the wheel, above the shoes. Its function is to exert force onto the shoes so as to bring them into contact with the drum and stop the vehicle with friction . [ 2 ]
Generally speaking, a tractor trailer requires more brakes than a typical vehicle, so making the brakes as simple and as cost effective as possible is very important. [citation needed] S-cams are very efficient at keeping brakes maintained because as the brake pad wears, the S-cam rotates more and causes the pads to further.

Compared to modern disc brakes, drum brakes wear out faster due to their tendency to overheat. The disc brake is a device for slowing or stopping the rotation of a road wheel. A brake disc (or rotor in U.S. English), usually made of cast iron or ceramic, is connected to the wheel or the axle.
This describes the electrically controlled drum brake principles. The brake is built with the brake shield (1) as a base that contains the mechanism. The brake shield is mounted on an axle/spindle using the holes in the centre. The brake shoes (3) are the items performing the braking by pressing outwards at the drum that covers all the innards.
