Simple trick, after you've pull the caliper off the rotor, using a large "C" clamp, compress the piston back down into the caliper. You can use the old pad and the back of the caliper as your compression points. The piston will have moved forward in the caliper as the old pad has worn, and it will be almost impossible to put the caliper back on the rotor with the new pads without first seating the piston back down in the caliper. Once the piston is seated, and the new pads installed, they will easily fit over the rotor. While you've got the calipers off, its always a good idea to check and repack your front bearings. Pull off the dusk cap, pull the cottor pin, undo the bolt holding the rotor on the spindle and pull the spindle off. If the bearing are dry or rusty, etc. It's probably a good time to replace your bearings. A lot of time you get a new inner race with new bearings, but if your old race is in good shape, you really don't have to replace it. (plus is a pain to remove). Just repack the new (or old) bearings and replace everything back on the spindle. As for the rears; can't offer any better advice that what Brad did. As for time; the first side takes a little while, but the second will be done is less than a hour. Good luck.
