Rear Brakes

I have a 06 Express and i'm changing the original brakes and rotors for the first time. Got the fronts all done but, the rears are being stubborn. What's an easy way to get the rear rotors off. It seems that the e-brake pads are getting hung up on the rotor as i try to pull it off.

Gotta beat and pry em off, then fix the e brake system, there are updated retainer clips.
