Intermittent Noise During Slow Braking - anti-rattle clips?

[PyrPatriot]

I am hearing intermittent squeeling while doing soft breaking, towards the end when I come to a stop. I can't reproduce it, and when it happens it is random, but always when there is mild deceleration and just before the vehicle comes towards a full stop. It is quite loud. Seems to be coming from the passenger rear. I've tried reproducing it, and it definitely does not happen during hard braking. After I hear the squeel, I try to brake like that again, and it doesn't happen.


The vehicle is coming up on its 20k mile maintenance on Tuesday. In the meantime I'll try some brake cleaner and see if that helps. Given the JL/JT is so new, any advice on what I should look for in the brakes and tell the service tech? I am not going to mess with brakes or such until it is past it's bumper-to-bumper warranty. But I do want to start thinking about issues for after (it's why I have the Factory Service Manual and have at least gone through it looking at what sections are where for reference purposes)


ETA: I do go off-roading on this vehicle. It's all county roads but as you can see from my profile pic some of the roads are in VERY bad disrepair and have sections going downhill on a mountain road made of rocks. Brakes get used generously to slowly go over ruts and washouts

A high-pitched squeal when not braking is usually the brake pad wear indicator or “squealer” hitting the rotor. This is a small tab of metal that is meant to scrape the rotor when it's time to replace your brake pads.

The rotors may be glazed. If they are, you could try getting them machined. I had this on a vehicle and nothing fixed the problem until I eventually replaced the rotors.

The sound is during breaking, tail end of it, at low speeds/smooth stop only

could be as simple as some type of contamination on the pads. I have seen tire shine compounds do this. Try getting the brakes hot ( multiple hard braking) but not to fade point. All lot of times this will burn it off. If you drive gently all the time it will aggravate this issue.

Semi metallic pads are known for this.

Just a thought. At 20K the brakes should not be worn to the point of replacement.

Especially if it is just one area the sound is coming from. Will try brake cleaner. I did try hard braking but only once, not enough to get them hot. Good suggestion on the tire cleaner possibility, at the car wash I do chose the tire option

So cleaned out the brakes with some spray, nothing fancy. Didn't help. Noise is so random and intermittent. I'll be driving through a drive through and hear it loudly (partly because of echo from the nearby wall) but trying to reproduce it in the same parking lot, nothing.

I broke out the factory service manual to see if there was some troubleshooting options. There's a lot, but sqealing noise isn't on the list. Going forward I looked at what it will take to replace the pads. Looks like I'll need anti-rattle clips. But I'm not finding any on any websites. Anyone have any leads on what I could use? I don't think anyone's replaced their brake pads yet. One guy has 70k miles on his JT and just posted his brake pads are at 50%. Some youtube channels have upgraded their calipers and pads to some $2k set but nothing about clips was mentioned.

I'm gonna try real hard to see if this is under warranty. Apparently it's happened from day 1 according to my wife but I couldn't hear it. I thought I heard it a couple weeks ago on a trail but thought it was the old WJ behind me. Now with the Jeep naked I heard it often enough.

SHOULD it be a warranty issue? 20k and brake pads going bad, with mild wheeling on county roads at worst? I'm easy on the brakes, drive 75% highway, etc.

to confirm, you want me to reach out if the dealership IS able to diagnose the problem? Is that for like a feedback thing? Or did you mean if they are not able to?
