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.
As the S-cam rotates, the two symmetrical brake pads are forced against the brake drum until the pressure is released and the brake pads return to their resting position. [ 3 ] The principle of the S-cam allows the brakes of big vehicles to be more compact and less moving parts, since it only relies on a rotating shaft.
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 ...
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 ]

More exotic design had four, eight or sixteen shoes. [4] Some motorcycles used finned and/or vented housings for additional cooling, the first of which was ...
When the driver pushes the brake pedal with his/her foot, the pistons inside the cylinder will activate. The activation of this piston will allow two brake shoes located within the drum of the brake to expand, thus generating friction to slow down and stop the wheel. Usually, this brake is located in the rear wheels of the vehicle, while the ...
