rear disc conversion on CJ7 with scout 2 dana 44
- Thread starter t481
- Start date
I did on a Waggy 44. Only real difference is mine is 6 lug and your 5 on 5.5.
I would suggest you look for a mid 70's-80's f150 or bronco 4x4 front rotor or even a later CJ rotor. Basically you want a slide on rotor with a 5 on 5.5 pattern that is about 11-12" diameter. In my case I used 99 C1500 rear rotors because it was 6 lug and the rotor hat was large enough to fit over the axle shaft flange and had enough off set to get my caliper mount on the axle tube.
I got some longer wheel studs, same knurl and thread size, just longer thread.
To maintain the proper load on the axle shaft bearing, I cut the stock backing plate down and used it as a spacer between the axle housing flange and the retainer.
I used a 84 caddilac eldorado rear caliper, has built in park brake, but they are pricey, any G or F body front caliper will also work, just no park brake. Then I made a simple weld on braket to hold the rotor. I am sure if you search speedway motors or a vendor like that, they will have off the shelf caliper mounts. I used 80's Monte-carlo front brake hoses to go from the caliper to the axle then just ran hard lines as normal.

here is what i did on my scout 2 44. because i used a narrow track waggy 44 in the front (which i converted to 5 on 5 1/2) i used all the same brake components on the rear to keep all the same parts, and make it easy to get parts from an auto wrecker if needed (gm parts are a direct crossover)
the rotors are held to the axle with studs (factory front studs fron a 44)
i had the back of the axle machined to fit the hole on the rotor so no machining was required for future rotors.
iused the stock front caliper brackets, enlarged the hole to fit over the bearing bulge, cut a notch to clear the axle tube, then slid into place. like the other poster has said, i cut down the backing plate to be a spacer. i then mocked it all together to get the position for the bracket, tacked it on, disasembled then welded out.

Hey T481, sorry, I don't have any part numbers. But the parts are the same used on any mid '70s 1/2 ton Chevy or blazer or late '70s early '80s full size jeep wagoner/cherokee. As the parts are all from the front of a vehicle, I highly doubt any e-brake set up will work. I had zero concerns about e-brake when I did this conversion, it was about doing it as inexpensive as possible, using parts easily accessible at auto wreckers and parts stores. Although I burned up a set of wheel bearings once in Colorado and the local parts store didn't have the dodge bearings I needed in stock....what do you do, lol
