The rear brake drum consists of several key components that work together to ensure effective braking. These include:

1. Brake Drum: The metal drum that houses the brake shoes.
2. Brake Shoes: These press against the drum to create friction and stop the vehicle.
3. Wheel Cylinder: The hydraulic component that pushes the brake shoes against the drum.
4. Adjuster Mechanism: Ensures that the brake shoes are positioned correctly as they wear down.
