I think someone
(the resident lazya$$) was going to do a Tech Article on this.
If you've done brakes before, the fronts are pretty straightforward - no surprises there. I didnít use a C-clamp to free up the caliper from the disc, I just grabbed it and jiggled it a bit and the pads released enough to clear the disc (both front & rear).
The rear disc brakes are a little different in that, as mentioned above, you donít push the puck back into the caliper like you do the front. This is important. It actually threads back in. You can purchase a tool from Sears or wherever, or you could build your own. As the resident tightwad, I grabbed an old cheap socket out of the toolbox and, using a Dremel, fabricated my own:
Here it is in action
It doesnít take much effort to screw the puck into the caliper, so the tool doesnít have to be made of titanium or anything Ė it just has to fit into the slots and have means of turning it.
Follow those instructions Archon provided and you'll be in good shape.
