TeraFlex Rear Disc ?

The kit lists for around $490 IIRC. I didn't pay near that amount. It ended up being about what most yards that I contacted wanted for salvage ZJ stuff.
DC4WD had a fantastic price on it. Shoot them an email and they'll give you a quote with shipping figured in.

Great Bones, thanks a lot. I'll get ahold of them on Monday.
 
I'm running the stock cables on my Explorer disc kit and the cable clamp trick worked fine, except I didn't fold the cable in half, I used the "u-bolt" piece of the clamp in the brake lever notch, then layed the cable in the ubolt parallel with the lever and then screwed the clamp together.....no issues after 2 years of use.....but what I've found is that the 89 XJ park brake lever doesn't have enough throw to engage the e-brake firmly. The rig will still move with the e-brake lever pulled all the way, which I have not been able to adjust to correct.
I doubt this is cable length issue, more a lever travel....I've toyed with ideas of a cam mod to the lever, or mid linkage, that increase the throw, but haven't devoted much time to it. I need to resolve this, I may really need the e-brake sometime and not have it.
 
About 3 years ago I installed the TSM disc brake conversion for my 8.25 on my 98 XJ. There are a few minor mods that needed to be done to get it working right. The newer style dual diaphram vacuum booster found on 95+ XJs helps actuate the disc brakes properly where the older style may not.
I believe NAXJA has a copy on file of the article I wrote explaining the installation.

Chuckles, my rear discs work well .......it's the internal drum parking brake that 's the issue. Based on my experiences with the TSM setup........the kit creates way more suction than a dual vacuum booster!

I finally got around to doing my cables. I used the "Explorer Clevis Kit" that I put a link to above. I also reused my YJ cables. I had to drill a hole in the side of the clevis and cut a slot to the existing hole. Once I slipped my cable end into the clevis, I hooked everything up and found that there was too much spring on the cable at the brake end. It was binding up pretty bad. I removed about half of the length of the spring. I probably should have only removed a third but it still works fine.

At the e-brake handle end of the cable I was nervous that the cables would be too long. When I got it adjusted though there was about 1" of available thread left on the shaft thingie that the two cables mount to.

It seems that I have to pull the brake handle further to fully engage the brakes. I think they just have a longer travel distance to engage. They work like they should though. The handle is a easier to pull as well. Now the wife can actually set the ebrake.
 
As for increased handle throw, here is what I did: I don't have any pics of it, but on my old '92, I had bolted an angle iron piece to the bottom of the tranny tunnel and made a 2-3" swinging piece bolted to that. I then connected the handle output to the center of the swinging piece and connected the cable adjuster to the bottom. This increased the distance that the cable is pulled compared to the distance that the handle is pulled. It did however decrease the mechanical advantage of the stock setup a bit. I did this when trying to get some Hearst Airheart mechanical calipers working on a set of stock XJ rotors. The whole system never worked that well, so I ditched the parking brake setup and just ran with small chevy front calipers as rear brakes for a number of years without parking brakes. I have since changed to a Waggy rear D44. I set it up with small GM front calipers using a weld on caliper mounting bracket (modified to be bolt on.) I'm using late model Chevy truck front rotors, but still don't have a parking brake. The GM calipers work well though for rear brakes. Just some more useless inf. Jeff
 
You've described a cam type e-brake actuation where the output is greater than the input. Bell crank units work in a similar fashion. I'm working on a version of this right now.......stay tuned.
 
Don't the ABS cherokees have discs? Has anybody just swapped those in?
