Hey guys, heres the problem, i attempted to remove my rear brake rotor and it seems to be stuck on the handbrake drum or the hub, im not really sure. i released the handbrake and i attempted to remove the rotor with the two screw holes, but they were rusted and the thread disappeared after about 5 seconds of screwing it in. i knocked it lightly to get the rust off and now it looks like there's a sandpit under my wheel. any help would be greatly appreciated
