Replacing brake drum linings

Some vehicles, especially base trim models, still use drum brakes on the rear axle. In the United States these systems are commonly referred to as drum brakes, and the friction components inside the drum are called brake shoes. Over time these brake shoes wear out and must be replaced. Many vehicles also use a separate set of small drum-style parking brake shoes that operate the parking brake system. Replacing brake drum shoes is typically more complex than replacing standard disc brake pads. The drum assembly contains multiple components including springs, hold-down hardware, adjusters, and guides that must be assembled correctly. Improper installation can cause uneven braking, noise, or improper parking brake operation. After installation the drum brake system must also be properly adjusted to ensure correct braking performance.
