81.50110.0144 Rear Brake Drum

1. Function

• Braking Action: The rear brake drum is a crucial component of the vehicle's braking system. It works by creating friction with the brake shoes (lining pads) to convert the vehicle's kinetic energy into thermal energy, thereby achieving deceleration or stopping.

• Heat Dissipation: The brake drum is typically designed with cooling ribs or fins to increase the heat dissipation area, preventing a decline in braking performance due to overheating during the braking process.

• Support and Fixation: The brake drum is securely fastened to the wheel hub, providing a surface for the brake shoes to mount against and create friction.
