Paully,
Just did it to my front brakes (new rotors and pads). Two bolts holding the caliper on. Once they are off the rotor just slides out. Have something like a large C-clamp handy to push the piston back into the caliper as the new pads are much thicker than the ones your taking out and you need the room to slide the caliper over the new rotor. Also, both pads in each caliper have a metal anti-squeel piece at the bottom that has to come out before you take out the old pads. Take note of exactly how they fit in before you remove them so you can put them back the exact same way.
