Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are built for drivers servicing front brakes on BMW models with M Sport brakes, including aluminum hat rotor and optional design full cast rotor configurations. The coated rotors are shipped dry and ready to install, while the pad compound is formulated for consistent friction and improved pedal feel from the first stop. This kit is a practical choice for BMW 335i front brake replacement, BMW 340i front brake service, and BMW 440i front brake maintenance where OE-style fit and finish matter.

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

What This Brake Kit Helps Address

• Front brake pad wear and reduced stopping performance
• Rotor rust and surface corrosion on exposed brake components
• Brake noise, vibration, and harshness during everyday driving
• Uneven pad bedding after rotor replacement
• Time lost cleaning oil-coated rotors before installation

Verify the brake package on the vehicle before ordering, since fitment is limited to the listed M Sport brake configurations and rotor styles. Clean the hub face, inspect caliper hardware and slide components, and follow the vehicle manufacturer’s bedding procedure after installation.
