Rear rotor not coming out. Advice needed.

[majidmo]

Guys,
I really need help with this one as it looks like nobody has experianced this issue.

I tried replacing my rear rotors yesterday following DIY posted on this forum but I was not able to take the rear driver side rotor out after removing brake assembly. I banged on it with a rubber hammer for half an hour but it looks like something is holding it back. When I pull rotor out, it comes out about half an inch on the right side and maybe quarter of inch on the left side but that is it. Also it does not rotate at all. Should it rotate freely? the DIY was saying it might rotate when trying to remove the retaining screw but that was no my experiance.

I think something on the left side of hub is holding it back but there shouldn't be anything there, correct? I ended up putting everything back.
