Hey everyone, I have a 1997 Maxima GXE and I'm having trouble removing the rear brake rotors. I removed the pads and calipers with no problem. The rotors seemed to jammed in place. I removed the cap in the middle but that didn't seem to help either, it seems like the rotors are stuck in place somehow...is it just from the rust? or is there something I'm missing??? Please help!

thanks!!
