Helped a friend with his Jeep about 2 years ago to replace the rotors
due to 

After removing the claipers and banging on the rotors a bit with a

Then we used a 2x4 to hit them from the other side with a 8lb sledge.
Finaly just got under it with another BFH and beat dents all in the
Eventualy POP!
They were silly stuck! Never seen that before! Even on my old 5ks that
sit for a year sometimes wating for some TLC.
Glad you got Er' Done!
