Product Details and Fitment Notes

DFC designed this brake kit for drivers replacing worn front brake components on BMW models with standard brakes, M Sport brakes, M Sport Package, and select aluminum-hat or full-cast rotor configurations. The coated rotor surface helps reduce corrosion during service and ownership, while the ceramic pad formulation is tuned for consistent braking response and improved NVH control. Part number 4512-31245 is a practical choice for BMW 230i front brake service, BMW 330i front brake replacement, and BMW 430i front brake maintenance where the listed brake package matches the vehicle.

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

Common Issues This Kit Can Address

• Brake noise from worn pads or fatigued hardware
• Uneven pad wear caused by corroded or stressed hardware
• Rotor rust and surface corrosion on exposed braking surfaces
• Reduced braking smoothness from worn or out-of-spec rotors
• Longer stopping response from aged front brake components

Installation Notes and Quality Assurance

Before installation, verify the brake package on the vehicle, including M Sport, standard brake, aluminum-hat rotor, or full-cast rotor configuration, since fitment varies by application notes. Clean mounting surfaces, inspect caliper condition, and follow proper bedding procedures after installation to help the pads and rotors seat evenly. Part number 4512-31245 is supplied as a front brake service kit for the listed BMW applications.

DFC GEOSPEC coated rotors include a 12-month warranty against defects in material and workmanship.
