Product Details

The DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware line is built around matched braking components for service work where rotor finish, pad formulation, and hardware condition all matter. The coated rear rotors resist rust better than conventional painted or zinc-coated designs, while the ceramic pads are post cured and scorched for stable friction performance and reduced initial bedding time. For Toyota Matrix rear brake service and Pontiac Vibe rear brake service, this kit supports a cleaner installation and consistent pedal feel.

Part number 4512-76146 is engineered for rear axle use and is a practical choice when replacing worn rotors, pads, and brake hardware at the same time. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Service Issues

• Rear brake noise, squeal, or vibration
• Rotor rust, surface corrosion, or uneven wear
• Reduced stopping performance from worn pads
• Brake pulsation caused by rotor thickness variation
• Uneven pad contact or sticking hardware

Installation Notes

Inspect calipers, slides, and mounting points before installation. Clean the hub surface thoroughly so the coated rotor seats flat, and follow the vehicle manufacturer’s torque specifications during assembly. The rotors are shipped dry and ready to install, and the coating is removed naturally by the brake pads during normal use.

Quality Assurance

DFC states that its rotors are machined to tight tolerances, inspected for critical dimensions, and checked for balance on vented designs. The rotors in this kit carry a 12-month warranty against defects in material and workmanship.
