Product Line Details

DFC GEOSPEC Coated Rotors are engineered for corrosion resistance and OE-level fitment, while the 5000 Advanced Brake Pads are formulated for stable friction performance across a range of driving conditions. The hardware kit is designed to restore spring tension and caliper movement characteristics that can decline as original components age. Together, these components support a more consistent rear brake service on BMW X3, BMW X4, and BMW X5 applications.

• Longer stopping distances from aged friction material
• Rust buildup on exposed rotor surfaces
• Excessive caliper movement from stressed or corroded hardware

Installation Notes and Tips

Confirm whether your BMW uses the optional full cast rotor design or the original aluminum hat rotor design before ordering. Some listed applications include a disc brake pad wear sensor, so verify sensor requirements during service. Part number 4512-31264 is intended for rear axle brake replacement and should be matched to the vehicle’s brake configuration before installation.
