• Uneven pad bed-in after a rear brake refresh

Installation Notes and Tips

Confirm rear brake configuration before ordering, especially on BMW 328i, BMW 220i, and BMW 230i applications with production-date or standard-brake notes. The rotors are shipped dry and ready for installation, which reduces prep time during service. Follow proper brake cleaning, torque, and bedding procedures after installation to help the pads and rotors seat evenly.

Quality Assurance

DFC machines the rotors to OE-style tolerances, inspects critical dimensions, and balances vented rotors as needed before final inspection. The rotors include a 12-month warranty against defects in material and workmanship. Part number 4502-31235 is part of DFC’s brake kit lineup for rear service on select BMW models.
