Frequently Asked Questions

Are these rear brake discs directional like the front ones?
Yes. High-performance BMW M rear brake rotors also feature directional internal cooling vanes. To effectively pump hot air away from the braking surface, the left disc (34212284903) and right disc (34212284904) must be installed on their respective sides
Do I need special tools to replace the rear brake discs on my F85/F86?
Because the F85 X5M and F86 X6M are equipped with an Electronic Parking Brake (EPB), the system must be put into "Service Mode" using a diagnostic scan tool before you can retract the rear caliper pistons and remove the rotors. Attempting to force the calipers open without a scan tool can damage the electronic actuators.
Do these rear rotors include the parking brake drum?
Yes, the inner "hat" of these Genuine BMW rear brake discs acts as the friction drum for your emergency/parking brake shoes, exactly as the factory designed
Can I reuse my old brake pads with these new rotors?
It is highly discouraged. Your old brake pads have formed microscopic grooves and ridges that matched your old, worn rotors. If you install old pads onto these perfectly flat new rotors, the pads will not make full contact. This results in terrible brake squeal, rapid uneven wear of your expensive new rotors, and dangerously increased stopping distances. Always install fresh pads with fresh rotors!
