no need to touch e-brake. Just remove the caliper (I think it's just 2 caliper bolts - upper and lower one) and take it off the rotor (just remember to hang it safely on the wire or rope so that rubber tubes will not be bended too much. After that the rotor will fall off by itself. It's really easy.
When you'll be putting new pads and rotors back - you'll need to squeeze rear caliper piston back in using special tool - that you can borrow for free in autozone or partsourse e.t.c. The thing is that rear piston goes inside while turning (don't just push it in - or you can brake the piston).
P.S. Also don't forget to install clips for pads (2 clips per pad). They help pad to slide correctly to and from the rotor.
P.P.S. You'll also need to lubricate the sliding pins (where the caliper slides) under the rubber covers. Also put special brake paste on the rear side of pads, where caliper touches the pad, so that there will be no unwanted movement/squicking sound. And also, installing the pads, always put pad sensor (metal thing that touches the rotors when pads are almost gone) on the inside pad and upside.
