Went to bleed my brakes today and both my front bleed nipples are mangled, i am going to have to force a socket over them to get them out. But before i attempt it i want to have the replacment nipples ready to hand. My question is dose anybody know the size and pitch of the front bleed nipples on a 03, 3.0 Z4 (not sure if they put bigger brakes on for the 3.0)
