What exactly comes in this ACDelco rear drum brake hardware kit?

The kit supplies the key replacement pieces that commonly wear or fail in drum brake assemblies. Each component matches the form and function expected for rear drum brake services so you don’t have to re-use old, fatigued parts.

• Automatic adjuster assembly sized for compatible rear drum applications
• Return springs that provide correct shoe retraction tension
• Mounting pins, retainers, and clips for secure shoe attachment
• Auxiliary fasteners and bushings needed for a complete hardware refresh

How does replacing the adjuster and springs improve braking performance?

Worn adjusters and weakened springs can cause uneven shoe contact, excessive pedal travel, or noise. Installing new hardware restores the mechanical relationships inside the drum, helping the shoes maintain consistent clearance and return properly after braking events.
