so my roommate has a marzocchi z1 with avid bb7 breaks, and when he mounted the brakes no matter what he did that calipers were off, so he set washers on the screws to that mount to the frame to get it to line up. now i'm setting up my bike and i've got a marzocchi 888rc and avid code brakes, and i'm having the same problem. is this a common problem or am i just doing something wrong. (also this isn't my first set of avid brakes, so i know how to align them
