How I do it in the JY. Granted I don't care about the Rotor or bearings:
1. Remove the Caliper
2. Remove the Cap, Cotter, pin and bearings, then pull off the rotor and hub assembly
3. Flip over and remove the rotor bolts completely
4. Place rotor and hub back on car with bearing in place; hand snug the nut
5. 5LB hammer and usually 1 wack and that rotor pops right off
I don't know why you can't do the same process, but use a rubber mallet.
