Product Details

DFC’s brake kit line is designed to simplify brake service by combining the major wear components needed for a rear brake job. The coated rotors are processed dry and ready to install, which helps reduce prep time during service. The 5000 Advanced pads are formulated for stable friction performance and are assembled with shims that support quieter operation. Part number 4512-31279 is a practical choice for drivers looking for a rear brake refresh on BMW X5 and BMW X6 models where OE-style fit and finish matter.

Compatible With: 2015-2019 BMW X6, rear; 2009 BMW X6, rear; 2014-2018 BMW X5, rear; 2008 BMW X6, rear with vehicle production date from 10/2008. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Service Issues

• Brake noise from worn pads or fatigued hardware
• Uneven rear pad wear caused by stressed caliper hardware
• Rust buildup on exposed rotor surfaces
• Reduced braking consistency from aged friction material
• Longer stopping response after rotor and pad wear

Installation Notes

Inspect calipers, slides, and mounting points before installation. The coated rotors are shipped dry and ready to install, and the non-directional finish supports even pad bed-in. For best results, replace worn hardware during the brake service and follow the vehicle manufacturer’s torque and bedding procedures.
