The service manual does not show/say how to remove, doesn't even have pic of rotor in exploded view - WTF?? I have removed caliper and 3 nuts off the stud to which the rotor is mounted. It wiggles but won't come off. I tried tapping round and round, pry bar and while tapping other side.......nothing. Rotor is bent from rock or ? Maybe previous owner beat with a hammer to try and remove? Need Help.
