  • The primary function of the Brake Drum is to create friction when the brakes are applied.
    
  • During braking, hydraulic pressure from the brake master cylinder pushes the brake shoes outward into contact with the inner surface of the drum.
    
  • Supporting the wheel bearings: The drum often serves as the mounting surface for the wheel bearings, which allow the wheel to rotate smoothly.
    
  • Heat dissipation: The cast iron construction allows the drum to absorb and dissipate the significant heat generated during braking, preventing excessive temperatures that could damage the braking system
