Product Details

DFC designed this brake service kit for rear axle replacement on BMW models that require either original-design aluminum hat rotors or the optional full cast rotor design, depending on the vehicle configuration. The coated rotor surface helps resist rust better than conventional paint or zinc finishes, while the machined braking surface is finished to tight tolerances for consistent contact. The 5000 Advanced pads are formulated for modern vehicle braking demands and are prepared to reduce initial break-in time. Part number 4502-31227 is a practical choice for a rear brake refresh on BMW 535i, 550i, 640i Gran Coupe, and 650i applications.

Installation Notes and Tips

Confirm whether the vehicle uses the original-design aluminum hat rotor or the optional full cast rotor configuration before ordering. This rear kit is intended for the listed BMW applications and should be matched to the correct axle position and rotor design. Clean the hub mounting surface before installation, and follow the pad bed-in procedure recommended for the friction material to help achieve even transfer and stable braking performance.
