Auto Systems and Repair: Brake Drum Replacement
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.
