    I know it can be done, but what problems will I run into. I have seen it before and cant remember what the guy told me I had to modify?

    I have a complete front brake system that has been laying around for about 2 years to go on. But, I havnt done it yet. And with going to the 44s, I think it may be time.

    Re: rear disk brakes, using all stock front end parts?

    I went with the Warn 12-bolt disc brackets ($100) and used the instructions provided. You can use either the S-10 front calipers (non E-brake) or the Caddy rear disc set up (with E-brake). Rotors are 88-91 Chevy full size 4x4 type (6 lug). Hoses I used came from a 86-92 Monte Carlo front. I welded a 5/8" grade 8 washer to the back side of the spring perch and used an E-clip to hold the hose in place. The other end bolts to the caliper. Bleeding the brakes required them to be unbolted and rotated so the bleeder screw would be at the top. Resetting the pressure differential valve (aka proportioning valve) between bleeds. Good luck. You'll notice a big difference in stopping.

    I will be doing this to a 14FF though.
    Same idea though.

    <font color=blue>You can but you need to use a spacer between the axle flange and the backing plate to center the caliper over the rotor.

    You will need to modify the bolt pattern in the backing plates to match the bolt pattern on the 14 bolt and I believe you'll need a spacer in between the rearend and the backing plate to get the caliper centered over the rotor.

    The big thing is getting the brackets. As for parts, go get standard 3/4 ton FRONT disc brakes, (calipers, pads, rotors) and mount them to your 14FF hubs. (you know the drill, drive out the studs and then mount the caliper and press the studs back in)

    Once that is done, now either use the front axle backing plate and redrill it for the 4 bolt pattern on the 14FF, OR, buy a bracket which does basically the same thing, OR build your own bracket. All of the home made type brackets that I have seen do need a spacer to push the backing plate away from the 14FF flange to center the caliper on the rotor.

    I made my own brackets when I did my conversion.

    Go to the For Sale forum and buy Misfits brackets. I bought and pair and they come with spacers. Some heavy duty stuff. Do a search on here, some one listed all the parts needed to do the conversion. I printed out the list but, I don't have it here with me at work. But, it did involve all stock parts or parts you could get at a parts store.
