Hello, does the rotor wiggle around at all, even if slightly?
Very odd, originally there are clips on the studs holding the rotor on, I assume they are off. If so and it spins and no wiggle, then yes, it must be rust stuck. PB is the best but we usually spray around all the studs and in the middle. Let it sit then hit very hard on the rotor hub face ( area where studs poke through) sometimes we have to hit there over over and then it pops loose. This is all I can think of. If the rotor wiggled slightly, I would maybe say the e brake shoes are ridged and holding it and in this case , not much to do but be sure e brake is as loose as possible, and then force is need till the rotor does come off. Wish I had more
sounds good, I thought there may be something else holding it on. Thanx
