Rear Disc Brake Conversion

[Ron]

Hi, I just found this forum.

I owned a 1976 CJ-5, which I believed to be 1975 made originally. Has anybody ever do a rear brake conversion to discbrakes? Of course with the emergency brake system as well.

Appreciate all information shared.

Regards,
Ron

Ron,
Welcome from snowy Nebraska this morning!

Chuck P. who's on this forum as Oldjeep has this on his website. Perhaps it will help.

Really appreciate your advise spark. I've surfed to the site you suggested and it explains conversion for Dana 41 Rear and Dana 21 Front. My CJ5 uses Dana 44 Front and Rear. I've convert the front using CJ7 stock disc brakes. For the rear conversion actually I can use the same stock materials from CJ7, however, the trouble is on the emergency brake system. I need the emergency brake mainly to handle steep downhills.

I currently also doing a restoration project on my CJ3A. I will keep the project posted.

Maybe you have another bright idea?

Dana 41 isn't that different from a 44 I didn't think.

I'd write Chuck an e-mail and ask him if it were me.

I'm headed that way with my '48 in the spring. The same mounting brackets used to convert a Dana 25/27/44 to front disks will bolt up on a rear 41/44.

If you want to have rear emergency brakes also, instead of Chevy truck calipers you would use Cadillac Eldorado rear calipers. These have the mechanical setup for the e-brake.

So img getting ready to do this, can I sue the jeep rotor on the rear?

That is my understanding, but I haven't tried it yet. Supposedly the Chebby truck and Caddy Eldorado calipers interchange....

WOW!!!!!!!!!! $50 for new jeep calipers.... time to get the ole rotor turner out again, and go to the junkyard!!!

Im startign to wonder if I cant sue the same stuff we use on 9inches in the racecar.

Basicly, we get a chevy 5 on 5 11 inch rotor ( from monte carlo etc..)
and redrill the hub, then we use monter calipers, with afco gm caliper mounts which weld direct to the axle tube.

In my case, id need a 11 inch rotor from a 5 on 5.5 vehicle, say a newer 1/2ton ford truck... or, the jeep caliper... put on the wildwood racing calipers we have, and the afco weld on brackets, do the same up front, if I could find away to mount it where nothing interfers, as the knuckle turns.

Speedway motors also sells metric gm calipers with the e-brake setup for around $100 each.
