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 drum brake is a vehicle brake in which the friction is caused by a set of brake shoes that press against the inner surface of a rotating drum. The drum is connected to the rotating roadwheel hub. Drum brakes generally can be found on older car and truck models.
S-cam's are only used with drum brakes because the cam pushes on the brakes which rubs against the rotating drum, and thus slowing the vehicle. [2] Drum brakes are favored on bigger vehicles because they allow more surface area in brake pads to get a heavier load slowed down more efficiently.
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]
Alternatively, in a drum brake, the fluid enters a wheel cylinder and presses one or two brake shoes against the inside of the spinning drum. The brake shoes use a similar heat-tolerant friction material to the pads used in disc brakes.
Another type of power brake installed in automobiles is called the drum brake. This type of brake, in general, will create some friction that will slow down the wheel. In this type of brake there is a brake cylinder that connects master cylinder to the drum brake via brake lines that transfer pressure from the master cylinder.

Drum brakes provide consistent braking in wet or dirty conditions since the mechanism is fully enclosed. They are usually heavier, more complicated, and often weaker than rim brakes, but they require less maintenance. Drum brakes do not adapt well to quick release axle fastening, and removing a drum brake wheel requires the operator to ...
