• 5000 Advanced ceramic brake pads with post-cured friction material
• Scorched pad surface to reduce initial break-in time
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
• Dry-processed, dry-shipped rotors ready for installation
• Hardware kit engineered with PTFE coating, vulcanized rubber, and stainless steel
• OE-style rotor machining with non-directional finish for smoother pad bed-in

Product Details

DFC’s GEOSPEC rotor coating is designed to resist rust better than conventional paint or zinc finishes, while the cast iron rotor construction is machined to tight tolerances for stable braking performance. The non-directional finish supports even pad transfer and quieter stops. The 5000 Advanced ceramic pads are formulated for consistent friction, and the hardware kit is built to restore proper spring tension and caliper movement on aging brake assemblies. This part number 4512-31145 is a practical choice for BMW 325i, BMW 325is, BMW 325e, BMW 325es, BMW 325iX, BMW 318i, and BMW 318is rear brake service.

Used For

• Rear brake noise caused by worn pads or fatigued hardware
• Uneven rear pad wear from corroded or weakened clips and shims
• Rust buildup on exposed rotor surfaces
• Reduced braking consistency from aged rear brake components
• Brake service on BMW 325i rear brake kit and BMW 318i rear brake kit applications
