Most newer brake systems have "groan" issues. Long story short, you used to ahve smaller, hotter brakes with semi-metalic linings - i.e. steel wool that did a nice job of keeping your rotors clean. They did not stop as well, lasted maybe 30k miles, squealed when hot, but they did not "groan".

Now you have "NAO" - Non-Asbestos Organic linings that last much longer, your brakes are bigger and cooler and better but the new linings leave lining material on your rotors.

I put Performance Friction linings on all my vehicles when I change the linings. They squeal when hot but they keep the rotors clean and stop great.

Maybe we're referring to different sounds. My brakes squeak when I'm going sloooow, a low sounding squeak. Just because you think it's bull, doesn't mean your right. Jeep has been using the same axles, brakes, and rotors for a while now, can't see how they can't see how it's an issue. To me it's works like it is intended, an audible for wheel spin during slow crawling.

My JK has done this from day one and it really annoyed me at first. Now I don't notice it near as much. After just a couple of minutes on the road its gone.

Has anyone tried changing to aftermarket pads and rotors to see if that makes a difference?

Chewbaca, yup, thats the sound. Lol! And for clarification, new jeep brakes are electronically controlled now... Ever have to jam them? It doesn't make that sound. Mine only do it when I'm crawling. Engineering a braking system to make that sound, on one of the most capable off-road vehicles in the world, is not that far fetched!

I hear it if I focus on it .. but it doesn't bother me because background noise becomes non-audible over time - its the way my brain is wired. I grew up near railroad tracks and after awhile you become acclimated to the noise.

I have tinnitus due to exposure to loud noises when I was younger... I ran open expansion chambers in the desert, watched top fuel dragsters, spent many years in clubs with loud music and operated large printing presses up through my mid twenties.

I don't even hear my ears ring unless I focus on it.

mine only does it when I first put it in gear. I can be in the garage and on level grounding, not moving... groooooooaaaaan

It's a Jeep thing I guess. I've learned not to sweat things like that, water on the floor boards, poor gas mileage etc. I just love it unconditionally

Solution? Yeah, trade in your Jeep. Both my Jeeps have done it. It's normal for the Jeep.

Thats also what ive heard is that its a jeep to jeep basis. most people have it, some people dont. If it was a design thing, everyone would have it, right?

EBC green stuff pads don't make a sound.
They make brake dust but it doesn't bother me, they stop better than factory pads.

I've never heard it either during normal braking. The only time I've ever heard it is when I go over a bunch of uneven road and the BLD kicks in briefly.

mine has been doing it since day 1, a little groan just as you move in reverse or drive after slowly letting my foot off the brake... thought it was just the new brakes breaking in... at 2800 miles, I took it into the dealer to check out... they said it was a common thing, and has to do with the rear suspension... will have to see if it is still there after getting a lift.

This is when I get it. Start the jeep, put my foot on the brake and put it in gear. That's when I hear it. If I put it in neutral, take my foot off the break, and then put in drive, I don't hear it.

Im gonna try that later today to see if i get the noise. If not, then it has nothing to do with the brakes, but rather some system that grips the pads when you shift? I have no idea which system tho.
