Detailed Description

Part number 4504-31106 is a brake service kit for BMW models equipped with M Sport brakes. The kit pairs DFC GEOSPEC coated rotors with DFC 5000 Advanced pads to address both rotor replacement and pad service at the same time. The rotors use a G3000/G11H18 cast iron specification, are processed dry, and feature a silver-gray coating that helps protect against rust while avoiding the cleanup associated with oil-coated rotors. The pads are formulated for consistent friction, with post-curing and scorching used to reduce initial break-in time. This part number 4504-31106 is a practical choice for BMW 230i, BMW 430i, and other listed BMW applications where OE-style braking performance and corrosion protection matter.

What It Helps Solve

• Brake noise caused by worn pads or uneven rotor surfaces
• Rust buildup on exposed rotor surfaces
• Longer stopping response from aged friction material
• Brake vibration related to rotor finish or balance issues
• Time lost during service from rotors that require extra preparation

Installation Notes

Verify the vehicle’s brake configuration against the fitment notes before ordering, especially M Sport brake equipment and rotor design details. This kit is listed for front and rear service on the specified BMW applications. The rotors are shipped dry and ready to install, and the pad material is prepared for reduced break-in requirements.

Quality Assurance

DFC states that each rotor is inspected for critical dimensions and balance, with vented rotors corrected as needed during production. The rotors are built to meet OE specifications, and the kit includes a 12-month warranty against defects in material and workmanship. Part number 4504-31106 reflects DFC’s GEOSPEC rotor and 5000 Advanced pad combination for service-focused brake replacement.
