Small tight coil springs are involved. It can be done with regular tools, but finesse is required otherwise, you could get hurt. Not by the coils, but by your hands hitting something metal when the coil or tool lets go. You basically really need a 4" flat screwdriver and a locking needle nose pliers. The locking pliers lock onto the coils and you pull them off one at a time. The locking pliers are also used to compress and twist the pad holder. The flat screwdriver is used to rotate the parking brake and pad adjuster. If you are doing the pads, might as well get the brake spring kit also. They are rather cheap. When you put the pads in, make sure you put the correct pad in the forward position. IIRC, the pad will have more material near the upper portion. This is referred to as the leading pad. Don't forget some brake clean spray. Get 2 cans and don't try to eat, breathe, etc the dust. It will get all over the place.
