Product Details

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is engineered as a complete brake service solution for drivers who want matched components from the same brand family. The rotors are cast to OEM-style G3000/G11H18 specifications, machined to tight tolerances, and finished with a non-directional surface to promote even pad bedding and quieter stops. The pads are formulated for stable friction behavior and assembled with premium shims to help control brake noise. For Audi A6, Audi A6 Quattro, Audi 100, and Audi 100 Quattro rear brake service, part number 4502-74079 provides a direct replacement-style kit for the listed model years.

Common Brake Service Issues

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by pad wear or poor pad-to-rotor contact
• Rust buildup on exposed rotor surfaces
• Reduced stopping consistency from aged friction material
• Extended service time when rotors and pads are sourced separately

Installation Notes

Verify rear axle fitment against the vehicle’s brake configuration before installation. The rotors are shipped dry and ready to install, which eliminates rotor cleaning before service. Follow standard brake service procedures, inspect related wear items, and perform a proper pad bed-in after installation for even transfer layer formation.

Quality Assurance

Each rotor is inspected for critical dimensions and balance, with vented rotors corrected as needed during the manufacturing process. DFC states that every rotor meets OE specifications and includes a 12-month warranty against defects in material and workmanship. Part number 4502-74079 is backed by that warranty coverage.
