Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a service kit for BMW X5 and BMW X6 brake replacement. The rotors are machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions and balance before release. The coating is designed to be worn away by the pads during normal braking, leaving the rotor ready for service without extra prep. The pad set is formulated for consistent friction, reduced break-in time, and improved pedal feel across everyday driving conditions. This part number, 4504-31045, is a direct-fit brake service solution for the listed BMW X5 and BMW X6 model years.

Common Problems This Kit Helps Address

• Brake pulsation from worn or uneven rotors
• Rust buildup on exposed rotor surfaces
• Noise during braking from aged pads or poor shim performance
• Extended stopping distance caused by worn friction material
• Uneven pad bed-in after rotor replacement

Installation Notes and Tips

Fits 2014-2018 BMW X5, front and rear. Fits 2015-2019 BMW X6, front and rear. Verify axle coverage and brake configuration before installation.
