A brake drum is a rotating, cylinder-shaped component of a vehicle's drum brake system . When the brake pedal is pressed, hydraulic pressure forces brake shoes to expand outward against the drum’s inner surface, creating friction that slows or stops the wheel. Key Components & Materials Usually made of Grey Cast Iron for its

The actuator that converts hydraulic pressure into mechanical force to move the shoes. A brake drum is a rotating, cylinder-shaped component

The assembly comprises several critical parts designed to handle high heat and mechanical stress:

These pull the shoes back to their original position once the brake pedal is released. Operational Requirements

Arced metal structures with bonded or riveted friction material .
