Yes, there's a gear on the back side of the rear calipers that you have to retract manually w/a 4mm allen wrench. DO NOT use a c-clamp to push in the rear piston or you'll damage them. I believe there's a guide in the how-to section on how to do this properly. You do everything else the same on the rear calipers as the front, except for the stupid manual retractor screw thing. But in order to get to it, you have to remove a plug w/something like a 12mm wrench first. Again, check the how-to section. They're basically the same rear brakes as the 90-97 Miata, so if you can't find the how-to here, you can check the miata.net for their how to on changing brake pads.
