I just did the Liberty rear disc brake swap, but got new Powerstop rotors, shoes, snd calipers rated for towing. Crown makes parking brake cables for 1984-1996 disc brake conversions that are a drop in fit (it’s intended for their upgrade kit but works with ZJ or Liberty rear disc brakes on XJ as well). Mounted the ZJ hose brakes on one of the leaf spring bolts. I am stunned by the increased stop speed on these. And the parking brake grabs so much better than the drum brake - only need to pull handle maybe 1/2 way, and it’s solid grab even on steep hill. Wow. Rear disc brakes are awesome for Cherokee!!

Experience talking here: When you do this, the zero dollar option after the install is to find your proportioning valve (next to or under M/C), remove the stud from the front, pull off the o-ring and reinstall the stud. This gives full pressure to the rear disk brakes. Failure to do this reduces the pressure to drum brake levels and therefore doesn't really improve the brakes. Of course an adjustable proportioning valve (Ebay, etc.) is also a great option.

If I ever get an XJ, and the brakes need replacement, I will do it. For now, I have a pretty sweet ZJ and it has ZJ brakes.

I know this is an old video, But when your trying to get that ebrake cable off. slide the box end of a wrench over the clip, Usually a 13mm and the cable clip will come out super easy.

Jeep has a way of making things so simple but every now and again you'll find some clip or bolt that looks like it was designed in a different universe. Lol like that e brake clip and the 2 bolts at the top of the bell housing that take an "E" socket like e35 I think

Anytime you have to bust out the welder, it is more than a “simple” project.

next step will be tha rear rotor and brake parts from WK, there will be more contakt surface between rotor and pads.

Well done I’m going to save this one. I’m thinking it is probably best to do this at the same time one would install a Torq locker, which sounds like a future project. And I assume that locker is still preforming well and was a good choice for the XJ. BTW in the warnings that you placed you did forget to include to mention California prop 65 🧐 Maybe next time, I actually have to include that silly warning with the XJ bags I make.

when you scavenge your parts either from a ZJ or the KJ 8.25 for your swap, remove the 4 studs from the housing that hold the backing plate on so you can re-use them on your housing so your studs arent too short. remove the plate, put the 4 nuts back on so you dont booger up the threafs on the stud before you pound them out with a hammer

When pulling the emergency brake if you get the proper size line wrench you can push it over there and it will push all the pins and at the same time

I did basically the same thing but didn't bother with the proportioning valve. WJ front brakes and KJ rears. I still need to try it on glare ice to see how the brakes perform, but its not looking like it is going to be a problem. Add a spare tire carrier with a 33" on it, and with that alone, you'll probably want the more rear brake bias.

You only need 3 threads for full bolt strengh. You could cut those down to half way down into the nut and as long as they are torqued its all gravy. I have my u bolts cut to 3 threads showing above the nut way easier to deal with then the way those long winded bastards are from the factory.

I wonder if you take 2 XJ body's cut them in half forward of the C pillar weld the 2 halves together make an "overland" trailer. replace one of the fuel tanks and use it for water. the other tank for spare gas tank.

Could that small part make the difference if I forgot that part??? Btw I’m trying to stop 35s still feels like stick brakes.

Can anyone recommend a soup-to-nuts kit that has all included components, without the need to hunt around?

I like my 8.8 swap with disk brakes better. :) Definitely do the ZJ proportioning valve, it makes a world of difference. I would drive backward and slam on the brakes and the front would lock up but not the rear. Once I swapped the internals of the proportioning valve they can lock up going forward.

The general consensus is that the disc brake proportioning valve allows less rear brake pressure, right? I have WJ fronts and KJ rears and left the drum proportioning valve alone. I need to wait until some snow falls so I can check the brake bias. If you want to keep the drums, I would recommend an aftermarket proportioning valve and tune it how you want it. Any significant amount of trailer tongue weight and the braking in 2wd is terrible with that setup.

First step is to mount the hose to the axle tube. You don't have to do it exactly as I did if you don't have a welder, just make sure it isn't going to contact anything and rub through. Then you need to shorten and bend the brake tube slightly to properly reach the ZJ hose.
