1. Drum: The drum is the cylindrical-shaped metal component that rotates with the wheel. It provides a braking surface for the brake shoes.
2. Brake Shoes: Brake shoes are curved, semi-cylindrical components made of friction material. They are mounted on a backing plate and press against the inner surface of the drum to create friction and slow down the vehicle.
3. Backing Plate: The backing plate is a metal component that supports and guides the brake shoes. It is attached to the axle or chassis of the vehicle.
4. Wheel Cylinder: The wheel cylinder is a hydraulic component that contains pistons. When brake fluid is applied, the pistons push the brake shoes outward against the drum.
5. Brake Adjuster: The brake adjuster is a mechanical device used to adjust the gap between the brake shoes and the drum. It ensures optimal braking performance and prevents excessive wear.
6. Return Springs: Return springs are elastic components that pull the brake shoes away from the drum when the brake pedal is released.
7. Brake Fluid: Brake fluid is a hydraulic fluid that transmits the force from the master cylinder to the wheel cylinders.
