Product Details

DFC GEOSPEC coated rotors are processed dry and ready to install, helping reduce prep time during a rear brake job. The coating is engineered to resist rust better than conventional paint or zinc finishes, while the rotor casting follows G3000/G11H18 cast iron specifications for durability and stability. Each rotor is machined to tight tolerances, finished for even pad contact, and inspected for balance and critical dimensions.

The 5000 Advanced ceramic pads are post cured for stable friction performance and scorched to remove uncured bonding agents. That process helps deliver more consistent stopping performance from the first stop. The included hardware kit uses PTFE coating, vulcanized rubber, and stainless steel to replace worn rear brake hardware components during service. If you are searching for a rear brake kit for BMW X3 2011-2014 or BMW X4 2016-2018, part number 4512-31288 is built for that application.

Common Brake Service Issues

• Rear brake noise, squeal, or vibration
• Rust buildup on exposed rotor surfaces
• Uneven pad wear from fatigued hardware
• Reduced braking smoothness during stop-and-go driving
• Longer pedal feel changes caused by worn rear brake components

Installation Notes

Before installation, confirm rear axle fitment by year, make, and model. Inspect calipers, slides, and mounting surfaces for wear or corrosion before assembling the new components. Clean the hub face thoroughly so the coated rotor seats correctly, and follow standard brake bedding procedures after installation. This kit is intended for rear brake service on the listed BMW applications only.

Quality Assurance

DFC rotors are 100% inspected for critical dimensions and balance, and every rotor includes a 12-month warranty against defects in material and workmanship. The brake pads are manufactured with post-cured friction material and premium shims, while the hardware kit is engineered to OE-style form, fit, and function.
