Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads, part number 4502-31242, are engineered as a rear brake service solution for BMW 430i, BMW 330i, BMW 328i, BMW 428i, and related xDrive and Gran Coupe applications listed below. The coated rotors are processed without oil, which reduces prep time during installation, while the pad compound is formulated for consistent friction and a shorter initial break-in period. This brake kit is a practical choice for restoring rear braking performance, pedal feel, and quiet operation on standard-brake BMW platforms.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Brake Kit Helps Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or rotor surface wear
• Reduced stopping performance from depleted friction material
• Rust buildup on exposed rotor surfaces
• Extended service time from rotors that require extra cleaning before installation

Installation Notes and Tips

Confirm rear axle fitment, brake type, and any production-date notes before ordering. For best results, inspect caliper condition, slide hardware, and brake fluid condition during service, and follow the vehicle manufacturer’s bedding procedure after installation. The dry rotor coating is designed to be swept away by the pads during normal use.

Quality Assurance

Each rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions to meet OE specifications. Vented rotors are balance-checked and corrected when needed. DFC backs the rotors with a 12-month warranty against defects in material and workmanship.
