I have a Scout Dana 44 rear axle in my 85 CJ7 that has an injected 5.0 Mustang EFI motor in it. It also has an NV4500.
When I got the Jeep it had the Scout Dana 44 and a SSBC rear disk brake setup (SSBC is no longer in business). I cannot leave it with drums as I have seen advised as I do not have any of the parts. I need to have a setup with an emergency brake.
I see a lot of information about caliper brackets but I do not see much about rotors.
The setup I have now mounts the Lincoln VII style caliper very low at about the 5 o'clock position. I want to switch the GM caliper setup so that I can get parts in the future.
I see references to using F150 rotors. I would like to find a rotor what would fit over the axel flange and also clear my 15" aluminum rims that I have now. What about the stock scout front 1-1/8 Scout rotors. I run that setup on the front axel with Chevy truck calipers and an aftermarket bracket and it is one of the best modifications I have made to my Jeep. If the Scout II rotor is too thick for the GM emergency brake calipers, what about 7/8" thick CJ7 rotor (like I took off the front for my brake conversion) that is used on the later CJ7s. I am willing to grind down brake pads if a rotor is a good match but a little too thick.
I have tried searching but either the links are dead or I run into some other problem. I would like to put a kit together myself so that when I need a part, I am not dependent upon someone to still be in business to get a rotor. SSBC no longer make the kit I have so I need to move on.
I do not mind turning the rotor inside the had if it is needed. I would even be willing to re-drill a 5 lug rotor because I believe that it would still be balanced when the new 5 x 5-1/2 pattern is drilled. I am unsure how good of idea it is to drill a 6 lug rotor to a 5x5.5 because of balance. I would like the rotor to be hubcentric when I am finished but I could make a spacer ring on my lathe if it is needed. The rotors I have now float on the lug nuts and are not centered and will require such a ring if I keep my current setup.
Any advice would be appreciated. Thanks.
