I got the one click kit from powerstop. But the necessary parts are a complete caliper with the correct brackets, so exactly how you see it in the picture I posted. and then the pads and rotors. I over researched it big time, but the powerstop site breaks it down very well. I got the KC2046 kit for the rear. If you search that on rock auto it even breaks down the components of the kit. Worst case I think what could happen is if you mixed and matched 2wd and 4wd parts or you get a caliper without the mounting bracket. That's why I went with the KC2046, on the powerstop site it even says it fits my truck so I knew I couldn't go wrong.
And I think I did a crappy bleed and I also believe I installed the calipers on the wrong sides, the bleeder screws are pointed down so they are below the brake lines. I'm gonna flip them around and re bleed this week sometime.:tableflip:
