Product Details

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is built for drivers who want a complete brake service solution in one package. The rotors use a protective coating that helps resist rust better than conventional paint or zinc finishes, while the dry-to-install design helps reduce prep time during brake service. The pads are formulated for stable friction performance and are assembled with shims to support quieter operation. This kit is a practical choice for BMW 640i Gran Coupe brake replacement, BMW 640i xDrive Gran Coupe brake service, and BMW 640i front and rear brake maintenance when the listed rotor design matches the vehicle.

Common Problems This Kit Can Address

• Brake pulsation caused by worn or uneven rotors
• Rust buildup on exposed rotor surfaces
• Noise during braking from worn pads or poor pad-to-rotor contact
• Extended stopping distance from depleted friction material
• Uneven brake feel during everyday driving

Installation Notes

Verify rotor style and pad wear sensor requirements against the vehicle’s original brake configuration before ordering. This kit is listed for front and rear positions on select BMW 640i, BMW 640i Gran Coupe, and BMW 640i xDrive Gran Coupe applications. Clean all mating surfaces during service, follow proper bedding procedures after installation, and confirm that the correct axle-specific components are being replaced on the vehicle.

Quality Assurance

Each rotor is machined to tight tolerances, finished for consistent pad contact, and inspected to confirm critical dimensions meet OE specifications. DFC states that every rotor carries a 12-month warranty against defects in material and workmanship. Part number 4504-31098 is part of the DFC GEOSPEC Rotors with 5000 Advanced Brake Pads program for service-ready brake replacement.
