Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a complete rear brake solution for vehicles such as the Bentley Continental, Bentley Flying Spur, Audi A8 Quattro, and Audi S8. The coated rotor finish is designed to fight corrosion while reducing prep time because the rotors are processed dry and installed dry. The pad compound is formulated for stable friction performance and reduced break-in effort, making this kit a practical choice for rear brake service on luxury sedans and grand touring models. Part number 4502-73121 is built to OE specifications for fit, finish, and braking consistency.

Common Reasons for Replacement

• Rear brake pulsation or vibration during stops
• Rust buildup on rotor surfaces or hat areas
• Brake noise from worn pads or uneven pad transfer
• Reduced stopping performance from worn rear brake components
• Service interval replacement on Bentley Continental, Bentley Flying Spur, Audi A8 Quattro, or Audi S8 rear brakes

Installation Notes and Tips

Fits 2004-2018 Bentley Continental, rear, except carbon ceramic rotors. Fits 2014-2018 Bentley Flying Spur, rear. Fits 2005-2010 Audi A8 Quattro, rear. Fits 2007-2009 Audi S8, rear. Verify rotor style and rear brake configuration before installation. Clean the hub mounting surface, inspect calipers and hardware condition, and follow the vehicle manufacturer’s torque specifications during assembly. The rotor coating is normal and will be removed from the pad contact area during initial use.

Quality Assurance

Each rotor is machined to tight tolerances, checked for critical dimensions, and inspected to meet OE specifications. Vented rotors receive balance correction when needed, and the kit includes a 12-month warranty against defects in material and workmanship. Part number 4502-73121 is backed by DFC’s rotor and pad manufacturing process for consistent rear brake service.
