The Gladdy has disc breaks but a mini drum set up for the ebreak.

Can't say I use my ebreak all that often to be honest.
Thanks! I don’t use it that often either. I do use it when parking on uneven terrain, loose terrain, or inclines/declines.

Yeah thanks but I've been through 3 cases, 3 case managers, and a supervisor, and you all tell me the same thing. No one cares.
We are sorry to hear this @koldfront_xj, please send us a message if you change your mind and need extra support at the dealership.

My wife has a 2021 Overland with around 75,000 miles on it. We haven't had any problems with the hand brake, but we don't use it that much. Only when parking on a hill and first gear won't hold it in place.

When I had my 2022 I had a recurring slightly different problem, after about 10k miles the e-brake handle would not lock, meaning it wouldn't engage at all. it was very random when it would occur and after yanking on it for 4-5 minutes it would eventually catch. I never bothered to do anything about it and eventually went to a 2024. but all the posts here about cables and adjustments make me think it could have been one of those factors.

Your Jeep's brakes do still work with the engine not running. Now you may have an additional problem where the stored vacuum in the brake booster is bleeding off while the vehicle is parked, thus resulting in a stiff pedal which requires more effort to apply the brakes, but the brakes will still work when you push on the pedal.
Something must be wrong then because I have rolled away countless times while pressing the clutch to start the Jeep, right foot firmly planted on the brake.

Have YOU adjusted the cable under the center console as @Rahkmalla suggested? Or are you just relying on the assumption that that was properly done during all these dealer visits?

The one (and only) time I had a looseness issue with mine I pulled the rear of the center console, adjusted it, and put two nuts back on the threaded rod to lock into place. Too maybe 15 minutes. Haven't had an issue since.
The issue wasn't with the cable; the cable has always felt tight. The issue was the brake drum and shoe not making contact, so even with the cable tight, the brakes were not engaged. That being said, yes, I have personally adjusted the cable under the console several times by tightening the 10mm nut, although these were all before the cable was replaced last August.

Wow…You have drums??

I’m not familiar with these Gladdy’s…but sounds similar to the YJ’s we’d worked on back years ago. The cable needed adjustment constantly. As @Thunderspud mentioned…. Adding additional nuts to lock down the adjustment. However, I do remember having to replace some inner parts of the drums because the cable would get hung up and the parts weren’t moving as they should. That was an old rusty YJ…… It became ‘dangerous’ while offroading. We eventually got rid of the drums and did a disc brake conversion.

Watch some Youtube videos about parking brakes/drum brake troubleshooting. You might be able to find the problem yourself and fix it yourself OR tell the dealership exactly what the problem is and have them fix it.
Sometimes…..you gotta give the dealership A CLUE or a nudge in the right direction, or else they’ll tear everything apart, charge you a fortune, and never get it fixed.
2021 MT Mojave here! Mine consistently needs adjusting. The other problem that I have is that it gets stuck on occasion and the only way I can get it to release, is to beat that ever loving crap out of it.
Yup, I've had that happen too. The handle has to be pulled up so high that you need to really beat on it to get the button/handle to release. That is what tells me there was too much slack in the cable; this was prior to the dealership replacing the cable under warranty last August.
Trust me, I've told the dealership EXACTLY what needed to be adjusted - the shoes at the rear. I just refuse to pay them another $229 diagnosis fee when all they need to do is adjust them. I tried myself a couple weeks ago and I could only get the passenger side adjusted, and it was too much to fuss with the cables back and forth to get the driver side adjusted properly as well.

Yea, it sounds like your handle is only connected to 1 of the 2 cables. I've had that before. Get underneath and tighten that shit up yourself is your best bet. You can actually see the part that needs to be adjusted from the top down without having to pull or loosen anything. If i get a chance and can remember after work I'll try to take some photos for you.
Interesting...so after doing some more tests this week, the brake does seem to hold the Jeep on an uphill slope. That is, when I'm facing uphill, the brake will engage after a few clicks (the handle is about halfway up), the Jeep will roll for a couple of inches, and then I can feel the brake lock. However, when the Jeep is facing downhill, I have to pull the handle all the way to the top and it does not hold at all, even on a 2 degree downhill slope. Wondering why it seems to hold uphill but not downhill; and that might explain why I was only able to adjust the shoes on the passenger side. I'll get down there and look at the cables where they sit on top of the rear axle a bit closer. Thanks!

It wasn't a big deal when I lived in Florida and 95% of the places I parked were flat, level ground. But since moving to Virginia, it seems that every parking lot (and every trail) has some sort of slope to it.

Mine worked until I left it set and drove though a water hole in 4lo,:facepalm: now I need new shoes, but plus one on just lifting the center counsel and tightening it up. Or just leave it in gear when parked, good practice anyway.
Haha oh yeah, my brakes were full of mud and all sorts of crap when I pulled the wheels/calipers to try this myself a couple of weeks ago. That probably had something to do with it. I do always leave it in gear when parked; that's how I learned to drive stick. Reverse when facing downhill, first when facing uphill. The JT Manual does say to do this also, so I'm not too worried about transmission damage. It just sucks to not be able to park with the Jeep running; makes it harder to use the compressor and winch on the trails.

If the brakes work sufficiently well when the engine is running then what's wrong is you're not pushing on the pedal hard enough. Again, you may also have an issue with the booster vacuum bleeding down, but the brakes will hold the vehicle in place with the engine off if you apply enough pressure to the pedal.

I've had similar issues with the parking brake being loose, even after adjustment by dealer. I always have to rely on keeping it in gear and it should not be that way.
