• Non-directional rotor finish supports even pad bed-in and smoother braking
• DFC 5000 Advanced ceramic brake pads with post-cured friction material
• Scorched pads reduce initial break-in time and improve first-stop response
• Premium rubber-steel-rubber shims help reduce noise and vibration
• Hardware kit uses PTFE coating, vulcanized rubber, and stainless steel

Product Details

DFC GEOSPEC rotors are machined to tight tolerances and built to OEM-style G3000/G11H18 cast iron specifications for durability and stability. The coated surface helps resist rust better than conventional paint or zinc finishes, while the non-directional machining pattern promotes consistent pad contact. The 5000 Advanced ceramic pads are formulated for stable friction performance and quieter operation, making this kit a practical choice for BMW rear brake service on vehicles such as the BMW 740i, BMW X5, and BMW X7.

This part cross-references common brake service applications where a rear rotor, pad, and hardware kit is specified for the same vehicle platform.

Common Issues This Kit Addresses

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by fatigued or corroded hardware
• Reduced stopping performance from worn pad friction material
• Rust buildup on exposed rotor surfaces
• Uneven pad wear from aged caliper hardware
