I am doing some brake work to my car, but the rotor will not come off. It seems to be frozen. I have the caliper off, the little hex bolt out, I have tapped it with a rubber mallet, but still no luck. Any suggestions?

Probably some rust or corrosion between the hub and the rotor. You can try it a couple of ways. Heat usually does the trick, but you have to be careful with the torch and only heat the rotor and tap the periphery with a real hammer(ditch the rubber mallet). A less aggressive method is spraying the center of the rotor, hub and lug bolt holes with penetrating oil, tapping the periphery with that hammer, it should come free.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.

I would use Jeff's advise only changing the pertinent verb from "Tap" to "Smack". Smack is just below Smash. Don't hit the outside brake area. Concentrate the impacts to the area around the center hub.

I would use heat as a last resort.

If you aren't going to reuse the rotor, the best way to remove it is with a large 2-arm puller. You can usually rent them from parts stores or tool rental shops. Depending how badly rusted they are, you may still need to use heat. I've never had luck trying to whack them off with hammers.

I have the car up on stands right now, calipers pulled aside and I am spraying Liquid Wrench on the holes (not in the holes but in the opening so it seaps between the hub and rotor. I am going to try that for an hour and then I will break out the universal adjustment tool.
Thanks!

Well, after lots of penetrating oil and lots of blows with the hammer it appears the rotor does not want to compromise it's position. I guess I will swing by my friends shop and let him heat it up for me. I am suprised that this car did not have a threaded hole in which you can stick a bolt into and pop off the rotor. Hmmm I guess 10 years of northern weather has taken it's toll on freezing the rotor. I looked over all my records I see no mention of ever having the rear rotors replaced, they still have a pinkish heck mark painted on them from when the car was built.

Go to Autozone or Pep Boys tomorrow and rent a big 2-arm puller. It will come off!

I do not want to ruin the rotor, it is still good.
