Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a matched brake service kit for rear axle replacement. The coated rotors resist rust better than conventional paint or zinc-style finishes, and the dry-to-install surface eliminates the need to clean oil from the rotor before assembly. The pads are formulated for consistent friction, with post-curing and scorching used to support predictable stopping response from the first stop. For BMW 550i GT xDrive rear brake service or BMW 750i xDrive rear brake replacement, this kit provides the core friction components in one package.

What This Kit Helps Address

• Rear brake pad wear and reduced friction material thickness
• Rotor rust, surface corrosion, and uneven appearance
• Brake pulsation caused by worn or uneven rotors
• Noise, vibration, and harshness from aging brake components
• Extended service time from cleaning oil-coated replacement rotors

Installation Notes and Tips

Compatible With rear axle applications only. Verify rotor style and vehicle configuration before ordering, especially on BMW models with original design aluminum hat front rotors or optional full cast front rotors noted in the fitment data.
