Disc Brake Rotor Removal

After seeing all the previous posts concerning how hard these rotors are to remove, I had to add my two cents and ask a question.
What I have is a 2003 Elantra--removed the two small screws securing the rotor, oiled the areas around the lugs and hub adn beat it with a huge rubber hammer.
I had no problem removing the caliper and bracket but couldn't break the rotor loose. So I oiled it up, let it sit for a half hour, and went to run an errand.
On my return, I found my son beating the blazes out of the rotor with my ball peen hammer! He hit it so hard it left ridges around the hub section of the rotor. The rotor was now free from the main hub but would only move about 1/4" outward and hang up. We then tried a gear puller to no avail. Is it possible he deformed the main hub and/or the lug bolts? It seems to be the only thing I can think of that's hanging it up. Any help or ideas welcome.

A bit late with a response but I have seen other posts complaining about rotor removal. I ran into exactly the same problem where it seems like the bolts tip inward and prevent the rotor from coming off even though it is loose. (2003) The rotors were scoring after about 2 years.

I used a heavy duty puller and dragged it off. I actually split off a piece of the rotor, about the size of a brake pad. I just moved the puller over to another part of the rotor and began pulling again.

The new rotor went on without a problem, therefore the old rotor was bad. Could the deformation have been caused by over-tightening of the lug nuts?

I replaced the rotors and pads with Raybestos QS and they seem the wear very evenly.

Next time I would get it back to a dealer for the removal if the same symptom came up.
