As posted in the Tech section a couple of weeks ago, I completed a disk brake conversion for the Jeep D60 rear found on the J20 trucks. The documentation is completed and is in .pdf format for Acrobat Reader.
The fabber/seller also sells complete disk brake conversion kits for the GM 14B FF, pre-94 Dodge D60, and Ford D60. He may also be looking into selling complete bolt on disk brake conversion kits for the rear D44 and AMC20.
Here is the documentation: Jeep D60 disk brake conversion
If you have any questions that are not addressed in the documentation, feel free to PM or email me.

Great writeup! Makes one want to do it just for the heck of it!

A few questions that you might answer in the writeup:

1) Where did you get the brackets?
2) Where did you get the discs? Are they just standard GM discs?
3) Why was no proportioning valve required? The new discs and the old drums require the same amount of fluid motion to activate?

On the front studs vs rear studs thing - I didn't get it...it looks like the old studs had more "grip" on them than the new front ones did What are you referring to?

hey jode,
i'll try to answer this quick so I can go home.
1. The brackets as well as the entire conversion kit (everything) came from a seller yet to be announced.
2. Those are standard 3/4 ton Chev rotors.
3. When I say no proportioning valve, I meant in addition (tapped in) to the combination valve already present on our FSJs.
4. The old studs do have more grip...closer to the base of the stud. If you look closer, the ridges on the new (front) studs are closer to the threads. i probably should have made a close up of that image.

Jode,
I got home and found the original image of the wheel studs. I blew them up and re-attached to the .pdf.
That definately gives a better view of the differences.

How much for just the brackets and hardware? I can come up with rest of my own parts. Also, are there other brake caliper options? Is it just the GM style calipers that can be used for this application? Thanks for the detailed write up. It looks great.

Clem,
He hasn't given me an answer as of yet on selling just the brackets. I'll find out before he starts selling the kits.
As for the calipers, I'm not aware of other calipers that will fit. There may be, I just don't know.

Very nice job, well detailed.
Question: What bearings are you greasing? Axle bearings are supposed to run in gear oil.

Is there anyway that 15" rims can be used?

Did you do the parking brake hookup?

steve,
1. with the axle bearings, that was something i wasn't clear on. i have read in the past that the gear oil would lube the bearings. but, since my d60 had tube seals at the carrier bearings, i assumed little if any oil would be getting to the wheel bearings. that is why i greased them up.
2. i'm sure 15 inch wheels could be used. but, that would mean grinding down the calipers...of which i have no expertise. or, using wheels with like a 2 inch backspace. that kind of backspace would be hard on the wheel bearings. i have seen others do it though.
3. i haven't hooked up the parking brake as of yet. i have to find the modified cables first.
