To the best of my recollection, the rear brake pads are held in place with an anti-squeal bracket. The bracket sits on the top of the brake pads, then the pin gets tapped back in. It's really simple and I changed my rear brake pads in about 20 minutes. You don't have to remove the caliper, just tap the pin out, lift off the bracket, and replace the pads.

Good luck,
Tom
