brakes are VERY easy. when you unbolt the caliper, only unbolt ONE side (I think the top is easier) and just loosen the bottom bolt a bit so that the caliper will swing off the rotor...then you can just pull the pads, remove all the clips (if your new pads didn't come with new ones) clean them, grease them, and put them on the new rotors.
Then just wedge the piece of wood into the caliper and use it as a lever to push back the pistons a bit (don't to it too much) drop in the new pads and you're done! bolt the caliper back on and off you go.
the first one might take you about 30 minutes, but once you figure it out, it shouldn't take more than 10 minutes each for the others.
when I did mine, I also installed the SS brake lines and painted my calipers...so it took a bit more time, but if all you're going to do it replace the pads...its VERY easy.
there's a really good thread with pictures on scoobymods that I used.
