Whats up with the JK brakes "Groaning"
 
You hear these suckers, when you barely let up off the brakes?
I never heard groaning like this till I owned a Jeep.



Don't get me wrong, I think it's cool in its on way. Just curious on cause. Everyone I've driven is like that

I don't know why it does that when I back out of the driveway.... It was odd at first, but now I don't think about it.

Wait until your wheeling down a steep hill using the brakes. Talk about groaning.

Yeah mine only does it backing out of the driveway as well. The wife first commented on it when we first brought it home. Now we hardly notice it.

Iron Clad Lou 07-25-2013 02:48 PM

mine too...I only have 1k on the odo and I'm hoping this noise goes away at some point!

Adam1 07-25-2013 02:54 PM

I thought it was just me! 35k and still groaning as loud as it ever did.

BigManAndy 07-25-2013 03:32 PM

Been groaning since day 1.

Old Dogger 07-25-2013 03:46 PM

My 2013 from day one has also done it, but only when backing out of driveway!

kik 07-25-2013 04:19 PM

That's usually the sound when the Hill Start Assist is engaging/disengaging.

socal_rubi 07-25-2013 05:03 PM

Mine sounds like Chewbacca :)

No kidding!!!!


Can use the noise as a gauge on how slowly to let off the brakes
Lol

Nope. I have that turned off and mine still does it.

So the solution would be to pull it out of the driveway :)

My JKU brakes groan loudly right when a complete stop is being reached and right when letting off the brakes from a complete stop.

4500 miles on the clock.

Oh well, I guess its normal.

Mine do the same thing. About 8500 miles on mine.

Justgot2hunt 07-26-2013 02:22 AM

Mine as well out of garage/driveway. As son as I saw this thread I felt better (only 500 miles on mine so far).

chcg12 07-26-2013 06:09 AM

Mine too since day one-9k miles now.

Miser 07-26-2013 06:23 AM

Backing out of driveway from day one. It is annoying, but normal!
As of current, 3300 miles, and same sound as when new, no worse, or no better.

BB1857 07-26-2013 07:51 AM

Yup same here...i actually like it when trail running because it gives me a better idea of how much to come off the brake when on a steep descent!! plus it always give my passengers this--->>:eek:

Are these all automatic transmissions? I've heard other cars groan, but they've all been autos at idle since they want to go forward. I haven't heard a manual transmission vehicle do it.

HOOCBB 07-26-2013 08:12 AM

Mine doesn't do it that I know of. I'll pay closer attention next time to verify.

Morgan 07-26-2013 08:13 AM

mine does it only when its raining, almost sounds like the metal tab hitting the rotor when the pads are worn down, but a lot deeper sounding.

michiganadam 07-26-2013 08:18 AM

mine doesnt groan and never has

manuals will do it too if you are stopped on any incline and you have to press the brakes to keep the vehicle from rolling.

I thought all vehicles groaned if you let the brakes "slip"

Different brake pad material will have different effects I suppose.

First time with a Jeep and I wonder if the braking would benefit from a brake line upgrade to stainless steel braided. Less modulation of the brake force and more discrete pressures that would translate into better braking feel and less "slipping" of the brakes??

I know a lot of people upgrade to stainless steel brake lines. Maybe there is something to it.

I was told by a long time jeeper and jeep dealer that they added the sound feature for trail crawling... It gives an audible sound to indicate tire movement over rocks or on hills when crawling is needed. I was led to believe this was an intentional addition. I love it on my Rubicon when navigating rocks.

If you buy that, I've got a resort to sell you in Nuevo Laredo, MX.

I like that answer


Good one to tell non-jeepers
