What This Brake Kit Helps Address

• Rear brake noise from worn pads or fatigued hardware
• Rotor rust and surface corrosion on exposed braking surfaces
• Uneven pad wear caused by aged clips and hardware
• Longer stopping distances from worn friction components
• Brake vibration related to rotor finish or wear

Installation Notes

Confirm rear axle fitment against the vehicle’s brake configuration before ordering, since the listed BMW Z4 applications include multiple rear rotor notes. The rotors are shipped dry and ready to install, which eliminates rotor cleaning before assembly. For consistent results, inspect caliper condition, guide pins, and mounting surfaces during service.

Quality Assurance

DFC machines the rotors to tight tolerances, applies a non-directional finish for smoother pad bed-in, and inspects critical dimensions before release. Vented rotors are balance-checked and corrected when needed. The rotors include a 12-month warranty against defects in material and workmanship. Part number 4512-31189 is built for rear brake service on 2003-2008 BMW Z4 applications.
