Hey guys! I've got a broken lug bolt and am in the process of getting to the hub to remove it. I need to remove the brake rotor and for some reason it will not come off. I've done some searching, read some write-ups, and it looks like the rotor should simply slide off the hub for easy removal but for some reason mine will not do so. The only thing i can point a finger at, besides the possibility that the broken bolt is at somewhat of an angle keeping the rotor from sliding off is the small black circle around the piece of the hub that is sticking out. Below is a picture of what the brake rotor currently looks like. Do you guys see anything that must be removed? I'd get a manual but the vehicle is imobile, obviously, and the roomates are all at work. Need to fix this up so i can get to class come Tuesday! Any help is much appreciated!!
