• Dry-to-install rotor coating helps resist rust and reduces prep time
• Non-directional rotor finish supports even pad bed-in and smoother stops
• Post-cured, scorched pads are engineered for stable friction and reduced break-in time
• Premium rubber-steel-rubber shims help improve noise, vibration, and harshness control
• OE-matched cast iron rotor construction for durability and stability
• Part number 4502-31137 for front brake service on select BMW models

Product Details

DFC GEOSPEC rotors are coated in a silver-gray finish that is designed to fight corrosion better than conventional paint or zinc coatings. They are processed dry and shipped dry, so they are ready for installation without additional cleaning. The rotors are machined to tight tolerances, finished with a non-directional surface, and inspected for balance and critical dimensions to support OE-level fit and function. The 5000 Advanced pads are post cured, scorched, and assembled with premium shims to help deliver stable friction and quieter operation from the first stop. This kit is a practical choice for BMW 430i, BMW 540i, BMW 740i, BMW 750i, BMW X5, BMW M340i, BMW M440i, BMW 840i, and BMW M550i xDrive front brake service where the listed rotor design and brake package match.

Common Brake Issues This Kit Can Address

• Front brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or degraded shims
• Reduced stopping performance from worn friction material
• Visible rotor rust and corrosion on exposed braking surfaces
• Longer service time caused by rotors that require extra prep before installation
