I was trying to take off my rotor today, and there are two phillips head screws that help hold the rotor in place, i got one out no problem, but the other one wouldnt budge.... not even after pb blaster and slight vibration from a tapping hammer. so i got out my cordless electric screwdriver and tried loosening it. the screw didnt budge and now its stripped. I failed inspection because i was missing a stud on the hub.. now i cant get it fixed because of a little 3/8inch screw... any recomendations on how to get that bastard out?
