Product Line Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads pairs DFC’s coated rotor technology with its 5000 Advanced pad formulation in one service kit. The rotor coating is designed to resist rust better than conventional paint or zinc finishes, while the pad compound is prepared for consistent friction and reduced break-in time. Part number 4502-73155 is a direct-fit rear brake solution for Audi A6, Audi A6 Quattro, and Audi A7 Quattro applications listed below.

What This Brake Kit Helps Address

• Rear brake wear that causes reduced stopping performance
• Rotor rust and surface corrosion on daily-driven vehicles
• Brake noise from worn pads or uneven rotor surfaces
• Pedal pulsation related to rotor condition
• Longer stopping distances from depleted friction material

Installation Notes and Tips

Confirm rear axle fitment before ordering, especially on Audi A6 and A6 Quattro models that require 356mm front rotors with Ate or TRW 2-piston calipers. The rotors are supplied dry and ready to install, which helps reduce prep time during service. Follow proper brake service procedures, clean mating surfaces, and bed in the pads according to standard brake-in practice after installation.

Quality Assurance

DFC machines the rotors to tight tolerances, applies a non-directional finish, and inspects critical dimensions to OE specifications. Vented rotors are balance-checked and corrected when needed. Each rotor carries a 12-month warranty against defects in material and workmanship. Part number 4502-73155 is built for consistent rear brake service on the listed Audi fitments.
