Product Details
The Centric GCX Elemental Protection line focuses on corrosion-resistant rotor surfaces for everyday brake service. On this rear disc brake rotor, the fully coated finish covers the disc area while the coated hat adds additional protection where rust commonly forms. The solid rotor construction and smooth braking surface support direct replacement service for the listed Buick Rendezvous, Pontiac Aztek, Oldsmobile Silhouette, and Pontiac Montana rear brake applications. Part number 320.66048F is a practical choice when replacing a worn or rusted rear rotor on these vehicles.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Problems This Rotor Can Address
- Rear brake pulsation caused by rotor wear or thickness variation
- Rust buildup on exposed rotor surfaces
- Noise from a worn or uneven braking surface
- Reduced braking consistency from a rotor at or near discard thickness
- Service replacement needs on rear brake systems for the listed GM models
Installation Notes and Tips
Verify rotor dimensions, hub fit, and bolt pattern before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake issues, and inspect pads, calipers, and hardware condition during service. Because this rotor is listed for rear applications only, confirm vehicle position before ordering. For best results, follow the vehicle manufacturer’s brake service procedures and torque specifications.
Quality Assurance
Centric GCX rotors are built with coated surfaces to help manage corrosion on the disc and hat areas, supporting long-term service in exposed brake environments. Part number 320.66048F is specified for the listed rear applications on 2001-2007 Buick, Pontiac, and Oldsmobile models.
