Brake Drum Replacement

A few modern cars still use drum brakes and, almost without exception, drum brakes are used on the rear wheels. The brake drum is attached to the wheel and rotates along with it. When the brakes are applied, brake shoes are pressed into contact with the brake drum, slowing the vehicle. The harder the brakes are applied, the more firmly the brake shoes are pressed against the brake drums, which makes the car stop faster.

A technician must remove the wheel to replace the brake drum. After the brake drum is removed, brake components are inspected for wear or damage. After the new brake drum is installed, the wheel is put back on and the brakes adjusted.

Brake shoes wear out over time and should be inspected periodically. Brake performance will be compromised if the brake shoes become contaminated with brake fluid or oil due to leaky seals or wheel cylinders.
