with all those other weirdos...
1. Impact Driver - Please do this. Buy one. I get 1/2 my hubs with those screws broken off and it's a pain to drill and retap them. Use the impact driver and a MAP torch (get them red hot) and those screws will twist right out.
2. As just mentioned, there's a couple of other threaded holes in the rotor. take any 8x1.25 bolt (your average 10mm) that you have laying around and screw it in one or both of those holes. Those are there to literally press the rotor off the hub.
Easy as 1,2
