Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a matched rear brake service solution. The rotors are machined to tight tolerances, finished for balanced operation, and inspected for critical dimensions before release. The coated surface helps resist rust on exposed areas while remaining safe for normal pad contact during braking. The 5000 Advanced pads are formulated for stable friction performance and quieter operation, making this kit a solid option for routine rear brake replacement on the Audi A8 Quattro and Volkswagen Phaeton.

This part number, 4502-73109, is built around rear axle service needs and is suited for owners searching for a rear brake kit for 2004-2010 Audi A8 Quattro or 2004-2006 Volkswagen Phaeton. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Kit Can Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or rotor surface wear
• Reduced stopping consistency from heat-cycled friction material
• Rust buildup on exposed rotor surfaces
• Extended service time from separate rotor and pad sourcing

Installation Notes and Tips

Compatible With 2004-2010 Audi A8 Quattro, rear. Compatible With 2004-2006 Volkswagen Phaeton, rear. Before installation, inspect calipers, slides, and brake fluid condition, and confirm rotor dimensions against the vehicle’s rear brake specification. The rotors are shipped dry and ready to install, so no cleaning of oil-coated surfaces is required before assembly. Follow standard brake service procedures and perform a proper bed-in after installation for consistent pad transfer.

Quality Assurance

DFC states that each rotor is inspected for critical attributes and that vented rotors are balance-checked and corrected when needed. The rotors include a 12-month warranty against defects in material and workmanship.
