• Hardware kit included for the rear brake service
• OE-style rotor machining with non-directional finish for smoother pad bedding

Product Details

DFC 5000 Advanced Brake Pads are formulated for stable friction performance and are post cured to help maintain consistency. The pads are also scorched to remove uncured bonding agents, which helps reduce the initial bed-in period. DFC pairs them with premium shims to support quieter operation and more controlled pedal feel.

The GEOSPEC coated rotors are processed dry and ready to install, with a coating that helps resist rust better than conventional paint or zinc finishes. They are machined to OE specifications, finished with a non-directional surface, and inspected for balance and critical dimensions. Part number 4512-31216 is built for drivers servicing BMW rear brakes with a matched rotor, pad, and hardware solution.

Compatible With BMW 125i and BMW 128i rear brake service applications, including 2008-2009 BMW 125i rear, 2010 BMW 125i rear with production-date-specific fitment, 2011-2013 BMW 125i rear, 2008-2009 BMW 128i rear, 2010 BMW 128i rear with production-date-specific fitment, and 2011-2013 BMW 128i rear. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Reasons to Replace

• Rear brake noise, squeal, or vibration
• Rust or corrosion on the rotor surface
• Uneven pad wear or reduced braking consistency
• Longer stopping distances from worn friction components
• Fatigued or corroded brake hardware

Installation Notes

Verify rear axle fitment before ordering, especially for 2010 BMW 125i and 2010 BMW 128i models that require production date confirmation. Clean the hub surface before installation, follow proper torque specifications, and bed the pads according to standard brake service procedure. The coated rotor surface is ready to install without additional preparation.

Quality Assurance

DFC rotors are manufactured to OE-style specifications and undergo 100% inspection of critical attributes. Vented rotors are balance-corrected when needed, and the rotors carry a 12-month warranty against defects in material and workmanship.
