What is the Purpose of a Brake Drum?
The brake drum is the surface used by the brake shoes to press to create friction and slow down or stop the vehicle. Brake drums are often found on the rear wheels of many cars. Here are some of its key purposes and functions:
Friction Surface
The inner surface of the brake drum is where the brake shoes come into contact when the brakes are applied. This surface is typically smooth and designed to provide consistent friction.
Heat Dissipation
Friction occurs when the brake shoes press on the inner surface of the drum. This friction turns kinetic energy (motion) into thermal energy (heat). To prevent overheating, the brake drum is made to disperse this heat effectively.
Housing for Brake Components
It also houses various braking components, including the brake wheel cylinder and return springs.
