Disk brake upgrade

Hi, I have a 76 CJ7 with drum brakes in the front. If I source an axle with disk brakes can I pull all the brake hardware off and install that on my CJ? I have a dual reservoir master brake cylinder (not power). Would that work? Can anyone point me in the right direction for instructions on this?

Thanks!

What is the other axle and what did it come out of? If it's a CJ Dana 30 you can but I think you'll have to swap from the knuckles out.

77 CJ-7- AMC 360, Edelbrock cam, MC2100, Fenderwells, CJ T18/D20, Chevy D44/EB 9" rear, Trutrac f/r, 4.11, SOA, 1.25 lift shackles, 35x12.50 BFG KM2s, Shackle Reversal

if you find an axle like that would need to pull the knuckle along with the disk brakes (the things that turns with the pivots to make the jeep turn left or right).


Your going to need either a new prop valve or new master because the difference in size of the disk vs drum brake cylinders. Im still a little unclear if you just have to change the master cylinder as i dont have mine working perfectly yet, so i would wait till someone else weighs in on that part.

hope it helped

I converted my 76 CJ5 narrow track front from drums to discs, using everything from the knuckles out, off an 84 CJ7 widetrack Dana 30.

I believe I have everything laying around here. Where are you located? If close by you can have the parts. All I plan to keep is the axles for spares.

Bummer,cause if you tore it apart I wouldn't have too and shipping would be null and void. I would be willing to sell it all too you if interested,but shipping may cost some....

You will need a special socket when you go to take the knuckle off and put it back on http://www.jeep4x4center.com/ball-jo...ch-t40207.html you can find it elsewhere also.

They say money can't buy happiness but it can buy Jeep parts...and Jeep parts make me really Happy.

Socket

Oh man thanks that would have been a bummer. Hey do you know if aDana 30 front (narrow track, welded diff, 3.54 gears,) from a CJ5 will fit on a CJ7?

CJ5 and CJ7 are identical other than things related to wheelbase. You can definitely use a CJ5 axle on a CJ7 and vice versa (and CJ8 as well).
