Product Details

DFC designed this brake kit to address the full rear braking service on the listed BMW platforms, including 2016-2022 BMW 740i rear brake applications, 2020-2021 BMW 840i rear brake applications, and 2019-2020 BMW X5 rear brake applications. The coated rotors are machined to tight tolerances, finished for consistent pad contact, and inspected for critical dimensions and balance. The ceramic pads are post cured and scorched to reduce initial break-in time, while the included hardware is engineered to restore proper spring tension and caliper movement.

What This Kit Helps Address

• Rear brake noise from worn or fatigued hardware
• Uneven pad wear caused by corroded or stressed brake clips
• Reduced braking consistency from worn rear rotors and pads
• Rust buildup on exposed rotor surfaces
• Longer service time from separate rotor, pad, and hardware sourcing

Installation Notes

Use this kit on the rear axle only for the listed BMW fitments. Verify whether the vehicle uses standard brakes, optional full cast rotors, or original design aluminum hat rotors before ordering, since fitment notes vary by model and trim. Clean the hub surface before installation, follow factory torque specifications, and confirm pad bedding procedures after assembly. For BMW 740i, 840i, X5, and X7 rear brake service, confirm the exact brake configuration against the vehicle build data.

Quality Assurance

DFC states that the rotors are manufactured to OE specifications, processed dry, and inspected for critical attributes before shipment. The rotor set carries a 12-month warranty against defects in material and workmanship. Part number 4512-31263 is built as a complete rear brake service kit for the listed BMW applications.
