Product Details

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line combines coated brake rotors with matched friction material for service work on rear brake systems. The rotors are machined to tight tolerances, balanced where required, and inspected for critical dimensions to meet OE specifications. The pads are formulated for consistent friction output and reduced break-in time, making this kit a practical choice for BMW 525i, BMW 528i, and BMW 530i rear brake service.

This part number 4502-31183 is listed for rear applications on 2004-2007 BMW 530i, 2004-2005 BMW 525i, 2006-2007 BMW 525i with 310mm front rotors, 2006-2007 BMW 525i with 324mm front rotors, and 2008-2010 BMW 525i and 528i. It is also listed for 2008-2010 BMW 525i rear applications for Mexico-market vehicles.

Common Problems This Kit Can Address

• Brake pulsation from worn or uneven rear rotors
• Reduced stopping performance from worn rear pads
• Brake noise caused by aged friction material or rotor finish issues
• Rust buildup on exposed rotor surfaces
• Longer service time from rotors that require cleaning before installation

Installation Notes

Install on the rear axle only. The rotors are shipped dry and ready to install, which helps reduce prep time during brake service. Verify rotor size and vehicle configuration before installation, especially on 2006-2007 BMW 525i applications with 310mm or 324mm front rotors. Follow proper brake service procedures and bed-in recommendations after installation.

Quality Assurance

DFC states that each rotor undergoes machining and 100% inspection of critical attributes to confirm OE-spec compliance. Vented rotors are balance-checked and corrected when needed. The rotors include a 12-month warranty against defects in material and workmanship.
