brake job on my 03

[Scarsman]

so moral of the story, the H2 uses its rear brakes more heavily than the front brakes.

How many miles on your truck, and did you get it new? Actually, the fronts do about 80% of the braking. Vehicles will generally go through two sets of brakes on the front for every one set on the rear. Unless there is something wrong, I would expect that the fronts have been done once already.

the inner pad was worn down to the metal. both of the rear Rotors could have been replaced

Did you just put new pads on with that rotor? If it got chewed up at all from being metal to metal that could be bad. I like to always have the rotors resurfaced with new pads. It makes for a lot less trouble with noise and other issues later.
