Centric Premium brake drums use OE-style castings designed for dependable performance and extended service life. Machined finishes give the drum a cleaner appearance through the wheels.
- OE-matched: Matches the original drum's fit, form, and function, and meets SAE International standard material for structural integrity.
- 100% mill balanced: Designed for vibration-free operation.
- Precision-machined friction surface: Designed for smooth operation and reduced noise.
- Black painted exterior: A black protective coating on the drum's exterior provides corrosion resistance.
A rear brake drum turns with the wheel and gives the brake shoes a surface to press against when you apply the brakes. Signs a drum may need replacing include a pulsating brake pedal, grinding or scraping noises, a scored or heat-cracked friction surface, or wear beyond the drum's maximum diameter specification.
Replacing both rear drums together as a matched pair is recommended for even, balanced braking. For engine-specific details, see the "Vehicles it fits" section.
