I need to redo the front brakes on this thing, and the rotors and calipers are unreal. THey are the biggest things I've ever seen on a half-ton pickup. My trouble is in getting brake lines, bearings, loaded calipers and rotors, as everything at the local Advance and AutoZone is too small. Someone suggested that my heavy half uses discs from a diesel C/K, but I didn't think diesels were offered in a 5-lug 1/2ton hub configuration. Any help would be greatly appreciated. I have listed all RPO codes on my glovebox. Can someone translate them for me, or tell me the most up-to-date RPO codebook for our trucks? Thanks!
