no, no, no, I was asking if the parking brake is even connected to the front brake system and if not is it possible for it to do anything to the front rotors, pads or anything there?
I was also saying that it sort of looks like the parking brake has it's own set of brake shoes and if these do not press the rear pads against the rear rotor then how does it effect the rear brakes? I'm just looking at the diagram posted so I'm trying to understand how the parking brake works on the M3. I don't see where it connects to the rear calipers, which is what I was expecting to see.
