Product Details

DFC Friction built this brake kit for drivers who want a complete rear brake service with matched components. The GEOSPEC rotors are machined to tight tolerances, finished for even pad contact, and inspected to meet OE-level dimensional requirements. The 5000 Advanced pads are formulated for stable friction performance and use shims that help reduce brake noise and vibration. This makes part number 4502-31233 a practical choice for BMW rear brake replacement on street-driven vehicles that need consistent stopping performance and clean rotor protection.

Compatible With rear brake service on 2012-2020 BMW 328i, 330i, 335i, 340i, 430i, and 440i applications, including Gran Coupe and xDrive variants listed in the fitment data. This part cross-references no additional part numbers in the provided data.

Common Problems This Kit Can Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or poor pad-to-rotor contact
• Rust buildup on exposed rotor surfaces
• Extended stopping distance from worn friction material
• Uneven braking feel during everyday driving

Installation Notes

Rear brake service on these BMW applications should follow the vehicle’s OE procedure and torque specifications. The rotors are shipped dry and ready to install, which helps reduce prep time during service. Verify the exact rear brake configuration before ordering, since fitment varies by model, year, and brake package notes such as M Sport Package, standard brakes, or rotor design type.
