Drum Brakes

Drum brakes consist of a friction material or lining that is attached to a steel shoe by glue or by rivets. In automobiles, when the driver presses the brake pedal, a hydraulic system (pressure caused by compressed fluid) causes the brake lining of the shoe to press against the inside of the drum, which stops the car. Once the driver lets up on the brake pedal, springs release the brake shoe from the drum, and the wheel is once again able to turn freely.
