Product Details

Part number 4512-31211 is engineered for front axle service on select BMW 3 Series and X1 models. The coated rotors help resist rust, while the ceramic pads are formulated for stable friction performance and quieter operation. DFC also uses a non-directional rotor finish and OE-focused machining tolerances to support even pad contact and consistent stopping feel. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Service Issues

• Brake noise from worn or corroded hardware
• Uneven pad wear caused by fatigued caliper hardware
• Rotor rust on vehicles exposed to moisture and road salt
• Longer stopping distances from worn front brake components
• Brake vibration from rotor surface irregularities or imbalance

Installation Notes

Install on the front axle only. Verify rotor size, caliper clearance, and vehicle production date before ordering, especially for 2007 BMW 335xi applications with production date notes. Clean the rotor friction surface before installation if needed, and follow proper bedding procedures after service to help establish even pad transfer.

Quality Assurance

DFC states that each rotor is inspected for critical dimensions and finished to OE specifications. The rotors include a 12-month warranty against defects in material and workmanship.
