since no one has mentioned bedding the pads. read the directions and bed your pads.
just as well, pick up some tubing and a boxed wrench to crack open your lines and drain the shitty fluid as you walk the caliper back.
i have this kit and its worked on everything from a frontier to a raptor to a silradooooo. and its cheap and much easier and a smoother motion
i would for sure tq ya bolts down. i was a dummy and on my last brake job one of my rear caliper bolts came loose and it was ****ing with my pedal really bad. it was going to the floor almost and barely stopping.
new bolt in and tqed to spec and the thing stops in the middle of ferguson MO without worries.
good luck, and go slow. its not a race.
