• Complete rear disc brake kit with rotors and pads
• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Dry-processed, dry-shipped rotors ready for installation
• G3000/G11H18 cast iron rotor construction for OE-style durability and stability
• Non-directional rotor finish for more even pad bed-in and smoother braking
• DFC 5000 Advanced pads with post-cured friction material and scorched surfaces
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
• Part number 4502-74139 for rear brake service on select Porsche Cayenne models

Product Details

This DFC brake kit is built around the GEOSPEC rotor line and 5000 Advanced pad line. The rotors use a protective coating that helps resist rust better than conventional paint or zinc finishes, while the pads are formulated for stable friction performance and reduced break-in time. For Porsche Cayenne rear brake service, this kit supports a cleaner, more efficient replacement process with components matched for the same axle.

Compatible With 2011-2014 Porsche Cayenne, rear; 2013-2014 Porsche Cayenne, rear; 2011-2014 Porsche Cayenne, rear with 360mm front rotors; and 2011-2012 Porsche Cayenne, rear with iron brake rotors. Part number 4502-74139 is also referenced for Porsche Cayenne rear brake applications where the front rotor configuration is noted in the fitment data.

Common Brake Service Issues

• Rear brake pulsation from worn or uneven rotors
• Rust buildup on exposed rotor surfaces
• Brake noise from aged pads or worn shims
• Reduced stopping consistency from heat-worn friction material
• Longer service time when rotors require extra prep before installation

Installation Notes

Install on the rear axle only. Verify rotor size and front brake configuration against the vehicle notes before ordering, especially on Porsche Cayenne models with 360mm front rotors, 350mm front disc brake rotors, or iron brake rotors. The rotors are shipped dry and do not require oil removal before installation. Follow standard brake service procedures, inspect related wear items, and bed the pads in according to accepted brake service practice.

Quality Assurance

DFC GEOSPEC rotors are machined to tight tolerances, finished with a non-directional surface, and inspected for balance and critical dimensions to meet OE specifications. Every rotor includes a 12-month warranty against defects in material and workmanship. DFC 5000 Advanced pads are post-cured and scorched for stable friction performance and assembled with premium shims for improved NVH control.
