I just got a new set all 4 rotors for my 02 wrx. Got the front ones on pretty easy few stuck bolts and a little soft mallet action. Then I went to take off the back ones and they wouldn't budge. I sat there for about half an hour hitting them with a soft mallet and nothing. I figured the back rotors would be the same as the front (just take off the caliper and they slide off.) But for some reason they dont want to move at all. Am I not trying hard enough or am I missing something like a extra bolt. Please, any help would be a life saver.
