if its a ten bolt you have to remove the caliper, it has 2 allen head bolts holding it on, then pull the locking hub out, once that is out of the way there is a snap ring in the hub, its a PITA, a couple small screw drivers and time can pull it, once its out you will need a 4 prong hub socket, use it to unscrew the hub nut, it will have a washer behind it, a magnet will get it out, then there is another 4 prong nut, unscrew it and the hub/rotor will come off, knock the studs out and the rotor will seperate
