Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered for drivers who want a complete rear brake refresh with components matched for the same axle. The coated rotors help resist rust better than conventional paint or zinc finishes, while the dry-to-install design eliminates rotor cleaning before assembly. The pads are formulated for stable friction performance and consistent stopping response, making this kit a practical choice for BMW rear brake maintenance.

Compatible fitment includes rear applications for BMW 740i, 740i xDrive, 840i, 840i Gran Coupe, 840i xDrive, 840i xDrive Gran Coupe, 540i, 540i xDrive, M550i xDrive, M850i xDrive, X5, X6, X7, 740e xDrive, 750i, 750i xDrive, and 750Li xDrive across the listed model years. This part number 4502-31247 is also listed for BMW rear brake service on standard brake and select original-design aluminum hat rotor setups, as noted in the fitment data.

This part cross-references no additional part numbers in the provided data.

What It Helps Solve

• Rear brake pad wear and reduced stopping performance
• Rotor rust and surface corrosion on the rear axle
• Brake noise, vibration, and harshness concerns
• Uneven pad bed-in after rotor replacement
• Time lost cleaning oil-coated rotors before installation

Installation Notes

• Fits rear axle applications only.
• Verify whether your BMW uses standard brakes, original design aluminum hat rotors, or optional full cast rotors before ordering.
• Some fitments note a disc brake pad wear sensor; confirm your vehicle’s brake configuration before service.
• Follow proper brake bedding procedures after installation for consistent pad transfer.
• Inspect calipers, slides, and wear sensors during brake service to confirm the system is operating correctly.

Quality Assurance

DFC rotors are machined to tight tolerances, finished with a non-directional surface, and 100% inspected for critical dimensions and balance. The rotors are covered by a 12-month warranty against defects in material and workmanship. The 5000 Advanced Brake Pads are post-cured, scorched, and assembled with premium shims to support stable friction performance and improved NVH characteristics.
