• Rear disc brake kit with rotors and pads
• DFC GEOSPEC coated rotors with silver-gray corrosion-resistant finish
• Dry-to-install rotor coating reduces prep time before installation
• Non-directional rotor finish supports even pad bed-in and smoother braking
• 5000 Advanced Brake Pads are post-cured and scorched for stable friction performance
• Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
• OE-style rotor casting and machining for dimensional consistency
• Part number: 4502-48075

Product Line Details

DFC GEOSPEC rotors are coated to resist rust better than conventional paint or zinc finishes, and they arrive dry so they can go straight into service. The 5000 Advanced Brake Pads are formulated for consistent friction, with post-curing and scorching steps that reduce initial break-in demands and support stopping performance from the first stop. Together, they create a service kit aimed at restoring rear brake function with matched components.

Compatible Vehicles

• Fits 1979-1985 Buick Riviera, Rear
• Fits 1979-1985 Cadillac Eldorado, Rear
• Fits 1980-1985 Cadillac Seville, Rear

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Service Issues

• Rear brake noise during stops
• Rotor rust or surface corrosion
• Uneven braking feel from worn friction material
• Longer stopping distances caused by worn pads and rotors
• Brake vibration related to rotor finish or wear

Installation Notes

Install on the rear axle only for the listed Buick Riviera, Cadillac Eldorado, Cadillac Seville, and Oldsmobile Toronado applications. The rotors are processed dry and ready to install, which helps reduce prep time during brake service. Verify rotor orientation, clean mating surfaces, and follow the vehicle manufacturer’s brake service procedure for pad bedding and torque specifications.

Quality Assurance

Each DFC GEOSPEC rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions and balance where applicable. The rotors are engineered to OE specifications and include a 12-month warranty against defects in material and workmanship.
