f-w-i-w, the XJ is the only thing I know that has self-adjusting brakes & that form of adjustment*, which I'd previously always associated with VW Beetles/Bugs, whereas many self-adjusting brakes have no external manual adjustment.
*yes, I know it was carried over to the hand brake on WJ's - but I'm trying to keep this simple.

|Fourspeedman||Yes, that is how they work. And yes, some are adjusted by the hand brake. Drum brake shoes rotate with the drum when applied. That is why there is an anchor pin that cannot move. The return springs are usually wrapped around the anchor pin. Drum brakes are also self-actuating. The rotation of the drum drags the shoes with it. The anchor pin stops the shoe movement and the shoes are wedged against the drum. Ever wonder why the secondary shoe is larger than the primary shoe? Because once the primary shoe stops against the anchor pin, the secondary shoe is fighting all the rotation of the drum and taking all the abuse. Anyone remember when cars had four wheel drum brakes? They stopped very well because all four wheels were self-actuating. Then along came power boosters and if you were not careful you could put your face right through the windshield. So when you are going in reverse and apply the brakes the shoes now rotate in reverse. If the brakes are adjusted right the self-adjuster can't move enough to do anything. But if there is enough space between the shoes and drum, the self-adjuster can move enough to turn the star wheel one tooth. So if you go in reverse often the self-adjusters should keep the brakes adjusted properly. Same with the "man brake" brake adjuster. Used every day it will keep the brakes adjusted. None of the women in my family know how to use it.|

|CJ7-Tim||Between road salt ruining everything but the tires, and cheap Chinese brake parts kits, I just gave up and adjust the drum brakes as needed when changing oil and/or rotating tires. The only rust free Jeeps I see are new or brought in from elsewhere.|

I dunno, Maybe it's because I pull the drums when I swap tires twice a year and check them and do minor clean, Maybe because I back down a hill everyday. Dunno, hasn't been my problem.
They seem to work fine for me.

|Fourspeedman||I have never known self-adjusters to work right. If they did all you need to do is go backwards and hit the brakes hard several times until they tighten up. That "should" adjust them but never does. I remove the self adjusters on all my cars. I can tell the drums need adjusting when my hand brake travel gets excessive. Then I just raise up the rear and adjust them.|

Of all the things I have had problems with over the years the Drum brakes are not the issue that has been recurrent. on my XJ's. I mean I do check them when changing to winter studs, Maybe a clean and Move them around to check for binding, add a bit of antisieze where needed, but that is kinda it Until I need to turn and replace shoes every 80- 100K or so.
I live in the mountains and tend to run very heavy 99.9 % of the time with lots of stuff in the Jeep.
I didn't know this was a "Thing".

Could always pull the disc brakes from a ZJ or Liberty (depending on axle) and upgrade. Then you don't have to worry about the adjuster at all other than the initial setup for the internal drum parking brake.
One day of work definitely beats out messing with drum brakes for the rest of the vehicle's life, at least if you ask me it is.

|kerian159||The adjusters work, I'm just not getting the click part to lock into it correctly.|

|Wyo||I have had good luck with adjusters but I also use antisieze at all the contact points.|

I don't think that cable makes any difference. Last time I did the rear brakes they were both broken, so I discarded them as never known XJ (or any other) so-called "self adjusters" to work.
I like CJ-Tim's adjustment routine but it's too organised/disciplined for me - & I don't think they need doing that often. I just do mine for inspection each year, unless it becomes obvious the e-break's not holding as well as it might or the lever's coming up far too high.

|kerian159||It appears that the cable is too long so I guess I'll be searching for a new brake kit (just replaced this last oct.)|
