Yes, the rears are different than the front. The pistons screw in as opposed to using a "C" clamp to compress them. You need a brake cube to do it. There is only one bolt holding the caliper. Once removed, the caliper pivots up and off of the rotor on the slide pin. It then slides inboard to remove it. You'll also have to remove the parking brake bracket. A FSM would come in handy if you have never done it before.
