Product Details

The DFC GEOSPEC rotor design uses G3000/G11H18 cast iron and is machined to tight tolerances to match OE-style durability and stability. The coated surface helps resist rust better than conventional paint or zinc finishes, while the non-directional machining supports even pad contact during break-in. The 5000 Advanced ceramic pads are formulated for consistent friction and are assembled with NVH-focused shims for quieter operation. This rear brake kit is a practical choice for BMW 740i, BMW 740iL, BMW 840Ci, BMW 850Ci, BMW 850CSi, and BMW 850i rear brake replacement work.

What It Helps Address

• Rear brake noise from worn pads or fatigued hardware
• Rust buildup on exposed rotor surfaces
• Uneven braking feel caused by worn rotor finish
• Reduced stopping performance from aged rear brake components
• Caliper movement issues related to corroded or weakened hardware
