The F10 uses a electrical brake unit to engage the parking brakes
This electrical unit needs to be retracted using the BMW computer system (ISTA) in the workshop to replace the rear brakes and it must then be put into a new mode to learn the new pads.
I dont believe this is required for the front brakes
