Brake Drum Operation:
The part of the drum brake system that fits over the wheel lug studs. It rotates with the wheel and is contacted by the brake shoes. When the brakes are applied, the wheel cylinder plungers expand and move the brake shoes outward causing the brake shoes to rub against the brake drum for slowing or stopping of the vehicle. The brake drum also absorbs and dissipates much of the heat generated by the braking process.
