how do you remove rear rotors?

hey y'all,
so i've replaced the front rotors before, but i am having trouble with the rears. I remove the calipers and the old pads, but i can get the old rotors off. is there something else i need to remove? thanks

Make sure the parking brake is off. It works like a drum brake on the inside of the rotor center section. If it is on, you will have a hard time getting the rotor off.

thanks, i got it off.
