Emergency Brake Problem

I have a 2012 JK, 2 door and with the E brake engaged, it still drives in reverse and drive. I took it to the dealer and they said they tightened it. I tested it before I left and it was better, but now three hours later it's back to the same issue. I've never had a car or SUV drive with the e brake on. Any help is appreciated. Thanks.

Eh, beats me. All the vehicles I've had before have driven to some extent with the e-brake engaged. Just make sure your vehicle is in gear when you leave it.

The parking brake is actually tensioned by a drum and spring pretty close to the end of the handle. The brake shoes are under the rear rotors. They are adjustable and are replaceable.

And welcome to Wrangler Forum.

When I replaced my ebrake cable in my 95 yj. It only stayed tight for about a week. Then I had to retighten it. I had to do this about 4 times until it finally stretched to its final length. Maybe because these are new cables, they need to be tightened multiple times? I wish I knew for sure.

There is no tightening on the JK. There is a spring loaded drum that keeps the cables tensioned.

Since it's under warranty, I'll call the service guy at the dealership and tell him the tightening he did today did not fix the problem. Thanks for your help.

My e-brake quit holding a short time ago and I found out that a bracket on the rear axle had broken. I'm at work so I can't post a pic but crawl under your rig and trace the cables to your rear axle. On each side of the axle just inboard of the wheels is a bracket that holds the cable. The one on my driver's side was damaged and I had it fixed and that solved my problem.

Oh, and by the way:

Thanks for the suggestion, Beastmaster. I'll take a look tomorrow. This is my first jeep, had it about a month, so I'm learning as I go along.

These e-brakes just don't hold very well IMHO. Both my Dodge Diesels held great even parked on steep inclines. My Jeep likes to roll away on the slightest incline.

Doesn't this sound like the fixins for a recall?
Just a matter of time before someone gets sued. That's weird that you can't adjust them. Is there no cable equalizer down the line somewhere? Or do both cables attach at the handle? I'm so used to my 95, things were much simpler then.

They can be adjusted but it is a PITA. You have to remove the center console and the adjustment is at the handle.

The ebrake gave me issues Since day 1.
Dealership took it in and adjusted them. a couple weeks later .. Same thing.
I replaced the rotors and had to turn in the adjusters. PIA trying to set them back up. I would get the shoes to drag and back off. Did this 3 times. Every time I pulled the lever the brakes would not release and lock up the wheels.
Finally gave up cranking the adjusters in and leaving it

I was messing around with the e brake this morning and if I pull way up on it then it holds, but it feels like it shouldn't be pulled up that far. Guess we'll see how long this holds for before I take it back to the dealership for another three day adventure.

Just another crappy Mopar part. My ebrake doesn't hold any more. The Jeep rolls away on the slightest hill. This weekend I'm tinkering with the rear axle, but task one is tighten the ebrake. The process is to remove rear wheels, remove brake caliper and there is rubber cover you pop off. Inside there is a little wheel you turn to adjust. Doesn't seem to hard... unless it doesn't work.

Let me know if it works out.

you can adjust your brakes Project JK has a nice write-up that i used to adjust mine.
Project-JK.com - Jeep JK Wrangler Resource ┬╗ Jeep JK Wrangler Maintenance Emergency/Parking Hand Brake Adjustment

In my experience most vehicles will go with the e-brake engaged if they have enough torque
