Dynamite Friction 4502-73143 Disc Brake Kit - Rear

Rear Brake Kit for Audi Performance Applications

The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit is a rear disc brake service kit built for select Audi applications. Part number 4502-73143 combines coated rotors and advanced friction pads in one package for a direct brake service on supported vehicles, including Audi A6, A6 Quattro, S6, S7, S8, and A8 Quattro rear axle applications.

Key Features

• DFC GEOSPEC coated rear rotors with a silver-gray corrosion-resistant finish
• Dry-processed, dry-shipped rotors ready for installation without extra prep
• G3000/G11H18 cast iron construction engineered to OE specifications
• Non-directional rotor finish for more even pad bed-in and smoother braking
• 100% inspected rotors, including balance checks on vented designs
• DFC 5000 Advanced Brake Pads with post-cured friction material
• Scorched pads to reduce initial break-in time
• Rubber-steel-rubber shims for improved noise, vibration, and harshness control

Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are designed as a complete rear brake service solution for drivers looking for OE-style fit and consistent stopping performance. The coated rotor surface helps resist rust better than conventional paint or zinc finishes, while the machined surface and non-directional finish support quieter operation and more even pad contact. The brake pads are formulated for stable friction performance and assembled with premium shims to help reduce brake noise.

This part number, 4502-73143, is a strong match for rear brake service on 2011-2014 Audi A8 Quattro, 2013-2018 Audi S6, 2013-2018 Audi S7, 2013-2018 Audi S8, and 2016-2018 Audi A6 or Audi A6 Quattro rear applications with the listed brake configuration notes. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Brake Kit Helps Address

• Rear brake rotor wear and pad thinning
• Brake noise from worn pads or uneven rotor surfaces
• Rust buildup on exposed rotor surfaces
• Longer stopping distances caused by aged brake components
• Brake pulsation related to rotor surface condition

Follow standard brake service procedures, including proper rotor cleaning of the friction surface only if needed and correct pad bedding after installation.

Quality Assurance

Each DFC GEOSPEC rotor is machined to tight tolerances, checked for critical dimensions, and inspected to meet OE specifications. Vented rotors are balance-checked and corrected when needed. The rotors include a 12-month warranty against defects in material and workmanship.
