you will need a few sockets, metric most likely(havent done brakes on mine). I would recommend a drain plug wrench so as too release pressure when pushing the piston back. If you do i would recommend priming the line, otherwise(when you have the caliper off) put one of the old brake pads on the piston. then apply the c clamp to the old pad and the other side of the caliper, and tighten. They are zero clearance and will adjust the first time you apply brake pressure. If you do prime the brakes, remember to not get any brake fluid on the body of the truck, it will destroy your paint. Also for bout the first 500 miles try not to slam on the brakes(ok if you have ceramic pads), it could cause the rotor to heat up before the pads seat, causing hard spots and damaging the pads. Also, are you either putting on new rotors or having them refinished? Dont put new pads on old rotors. hope that helps.
