I've been to the dealership 6 times regarding the same squeak in my 23 Gladiator High Altitude. They said "it's just some surface rust in the rotor" every time. That was when I had between 20k and 36k. They never figured it out. Well now have 47k and took it to the local Pep Boys figuring I was coming due on brakes and wanted them to check. The brakes still have atleast half a life left so I have them check all the clips and everything. Everything looked great. I told them about the squeak, and in less than 15 minutes, were able to determine it was the parking break. It is too tight or something. They "burned off" some of it via riding with the brake fully engaged. It worked for a short time, but you can tell if you pull the brake and drive, that noise is there. They will have to remove rotors to properly adjust the parking brake catch area, so I will go back and have that done, since I don't have jacks and ramps or the space to work on it myself anymore. Hope this helps
For what it’s worth my square went away after cleaning the slide hardware and where they sit on the calipers. No grease, no brake dust, quiet as a mouse. I don’t use the parking break and I found it still squeaked even after working the parking break brake a few times while rolling forward and backward.
UPDATE:
I had to replace my rear rotors and brakes for the squeak to go away. The dealer and an independent shop could not figure out what was causing it. Of course now I'm out of warranty so I had to pay up$$.
BTW, if you ever need just the clips, Mopar has them here:happy to report that replacing the brake pads and clips fixed the squeak on my Sport S. I also had the broken clips and it squeaked pretty much any time I was driving slower than 25mph
I replaced them with this Power Stop pad and clip set and haven't heard the lsqueak since, and it's been over a week.
