drum brakes
A form of friction brakes comprising two curved shoes that have a heat-absorbing friction material bonded to their surface. These shoes are pressed outward against the inside of a cylindrical drum that rotates with the wheel. Application of brakes forces the shoes out against the drum, and when brakes are released the spring pulls the shoes away from the drum.
