Hi I am wondering why I can't get these rotors off.

I've had the breaks + calipers off 3 times and had to re-assemble so I could get around. The drivers side is down to metal. Passenger side isn't far behind. I carry alot of heavy sound equipment often. But neglected it this year. Will check back breaks as soon as the front are done. Replaced the rotors 1 time B 4, and had no problem. This time I cant budge these... soaked the rotor and hub with WD-40 and still cant break/ pry the rotor loose! I'm afriad to hit the hub for fear of damaging the bearings... That costs a mint!
Will try again today! Any sugestions?
