Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a front brake service kit for select BMW 3 Series and 4 Series models with M Sport brakes. The coated rotor surface helps resist rust better than conventional paint or zinc finishes, while the machined, balanced, and inspected rotor design supports OE-level fit and stable braking feel. The pad compound is formulated for axle-specific friction requirements and is prepared to reduce initial break-in time. This part number, 4502-31238, is a practical choice for drivers servicing a BMW 335i, 340i, 435i, or 440i front brake system.

What This Brake Kit Helps Address

• Brake pulsation from worn or uneven front rotors
• Noise from aged pads or pad shim wear
• Rust buildup on exposed rotor surfaces
• Reduced braking response from worn friction material
• Longer service time caused by uncoated rotors that require prep
