Product Details

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is engineered as a complete brake service solution for drivers who want matched components from the same brake kit. The coated rear rotors are machined to tight tolerances, inspected for critical dimensions, and balanced where required. The pad set is formulated for consistent friction response and reduced break-in effort, making this kit a practical choice for BMW 740i, BMW 740iL, BMW 840Ci, BMW 850Ci, BMW 850CSi, and BMW 850i rear brake service.

This part number 4502-31143 is a direct-fit rear brake kit for select BMW models and is suited to routine brake replacement where rotor condition, pad wear, noise, or corrosion are concerns.

What It Helps Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or rotor surface irregularities
• Rust buildup on exposed rotor surfaces
• Reduced stopping performance from worn friction material
• Extended service time when rotors and pads are replaced separately
