Product Details

This DFC brake service kit is built for front axle service on the BMW X3 and pairs OE-style coated rotors with advanced friction pads. The rotors use a G3000/G11H18 cast iron specification, are machined to tight tolerances, and are inspected for critical dimensions and balance. The pads are formulated for consistent friction output and reduced break-in effort, making this kit a practical choice for a front brake job on a 2011 BMW X3, 2012 BMW X3, 2013 BMW X3, or 2014 BMW X3. Part number 4502-31271 is also listed as 4502-31271 for ordering reference.

Common Brake Service Issues

• Front brake pulsation from worn or uneven rotors
• Squealing or harsh brake noise during stops
• Rust buildup on exposed rotor surfaces
• Reduced stopping performance from worn pads
• Longer pedal travel caused by brake wear

Installation Notes

Fits 2011-2014 BMW X3, front. Verify rotor size and brake configuration before installation. Clean the hub face, inspect calipers and slide hardware, and follow the vehicle manufacturer’s bedding procedure after installation. The coated rotor surface is processed dry and does not require additional preparation before service.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE specifications, finished with a non-directional surface, and 100% inspected for critical attributes. Vented rotors are balance-checked and corrected when needed. Each rotor includes a 12-month warranty against defects in material and workmanship. DFC 5000 Advanced pads are post-cured and scorched to support stable friction performance from the first stop.
