    Got some questions about the swap. What rotors work? I think I've heard people using 4wd 3/4 front rotors. Could rotors be used from a 3/4 or 1 ton 2wd? Who makes quality brackets? What year caddy calipers have the ebrake? Thanks! /forums/images/graemlins/rotfl.gif

    Stock 8 lug front rotors. 2wd rotors will not work cause the rotor and hub are all one piece. 76-78 caddy eldorado calipers /forums/images/graemlins/thumb.gif

    Thanks for the reply! 76-85 Eldorado calipers all had ebrake capiblities could they be used, or is there some benefit to using 76-78? Thanks! /forums/images/graemlins/waytogo.gif

    The 76-78 ones where the only caddy's that were about the same size and weight of a k5 or burb to effictively use these calipers.

    They are also the only calipers that will fit over the rotor. The other GM caddy calipers fit a thinner rotor but otherwise are identical. The only difference between 76-78 and all others is the piston. /forums/images/graemlins/thumb.gif

    3/4 ton 4x4 front rotors

    search ebay for "great lakes offroad" for the brackets. he's about the cheapest and they come with hardware

    make sure you research using caddy calipers and hooking up the e-brake before you decide to use em. there are more parts to it than just the calipers and some can be hard to find.
    if you want an e-brake for function (not to pass inspections) look into a line-loc/roll control from summit or jegs

    Orion,
    Have you used these brackets and if so how do you like them? Yeah been researching the caddy calipers and I'll need to pass state inspection. Plan is to try to score them at a junk yard. Thanks! /forums/images/graemlins/waytogo.gif

    The brackets were as described in the auction. They worked great for me and most of the people on PBB use em.
    They were unpainted and the spacers needed a little bump on the bench grinder to clean up the ends. Other than that, no complaints.
