went to change my rear rotors and pads and can't get the rotors off. my ebrake was off so that's not it. i've never had a problem on what should take 30 minutes to do, but i don't see why they are froze to the ebrake assembly. i wacked at them w/ a hammer and still wold come off so i got the bright idea to use a sterring wheel puller and it di pull them, but the ebrake assembly wanted to come w/ them. a friend to me there's an oval rubber plugin the back, remove it and i should be able to loosen the assmebly yet there's no room to get a screwdriver in there or even see in there. anyone know what's up?
