Product Details

Part number 4502-73105 is engineered for rear brake service on Audi A4 and Audi A4 Quattro models in the 2005-2009 range. The GEOSPEC rotors use G3000/G11H18 cast iron and are machined to OE-style tolerances, then inspected for balance and critical dimensions. The 5000 Advanced pads are formulated for consistent friction response and are assembled with NVH-focused shims for quieter operation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Kit Helps Address

• Brake pulsation from worn rear rotors
• Reduced stopping performance from pad wear
• Brake noise caused by aged friction material
• Rust buildup on exposed rotor surfaces
• Uneven pad bedding after a rear brake refresh

Installation Notes

Confirm rear axle fitment before ordering, especially on 2005 Audi A4 Quattro applications with 321mm front rotors noted in the fitment data. The rotors arrive dry and ready for installation, which reduces prep time during service. Follow standard brake service procedures, clean all mating surfaces, and complete a proper pad bed-in after installation.

Quality Assurance

DFC states that each rotor is inspected for balance and critical specifications, and every rotor includes a 12-month warranty against defects in material and workmanship. The brake pads are post-cured and scorched to support stable friction characteristics from the first stops.
