I am swaping a Dana 44 with disks into a 72 CJ with drums and non boosted master cylinder. My question is what have others done to to power the disk brakes, can i stick with a non boosted system and just swap to a larger master or do i need to go another route. Looking for suggestions that you have tried and work.
"I did some research and found one person suggests to use 76-78 CJ Master Cylinder Manual brakes with front disc brakes"

Are you going to do discs all the way around or just up front? I'm assuming the D44 is up front?? Or are you looking to have some kind of disc/drum combo??

If this is what you are doing (wasn't sure from your description whether you were talking front or rear), this would be your best solution IMO. Might want to consider power brakes as a long term plan.

Sorry about that, this swap is in the front and it will be disk in the front and drum in the back. I am considering how hard it would be to find a way to hook a booster up but i just built a TBI for it last year and i am not sure what i have for vacume.
So at this time i would like to run manual disk/drum. It appears the 76-78 master was for that kind of setup and should work right?

If you're going to go through all the trouble, why not do discs all the way around?? In which case, you would use a 1969 Vette "manual" master cylinder, 1978 Eldorado rear calipers, and 79 F150 rotors in the rear, use weld on caliper brackets, than run the Summit proportioning valve to the rear as well. There, you have 4 wheel discs for under $200.
Good luck

I don't know why everyone thinks you NEED a power booster with discs. Completely un-necessary. Use a later model master from a CJ with manual front discs and install an adjustable proportioning valve to dial in the rears. Done.
Travis..
edit: another great thing about manual brakes is that they work the same whether the engine is running or not. This can be a great benefit.

Thanks that is great to hear, i will install one right away.
