    wj, I tried to quote you and respond in your quote but that obviously did not work.

    I hear it at low speeds starting from a dead stop. I do not notice it at higher speeds.

    I believe that is the same

    Hmm, I only hear at low speeds and do not notice anything when applying the brakes. Seems to happen from a dead stop.


    I honestly cant tell which side because I'm driving. My wife will not drive the Tahoe after I had some work done to it. I'll ask my neighbor to drive it while I listen this weekend.


    "If it appears to be a noise associated with the rotation of the wheel"

    I hope its not a bad hub.
    Could a warped rotor cause issues like this?

    This turned out to be a real mess of a quote haha​

    If noise is from a dead stop, your calipers might be hanging up but I know you just replaced them. I can’t remember if you said you replaced the rubber brake line. They can swell on the inside and restrict fluid and keep pads engaged longer. When you swap pads, might take a look.

    A warped rotor could make a similar noise but I would think you’d notice pulsations in your brakes when you stop.

    I didn't replace my calipers, I was going to replace them but decided to try cleaning a lubricating them first and see how that goes.

    I didn't replace any lines, yet. All stock right now. I will take a peak at them. I was planning on replacing my lines with SS lines but have not done it yet.

    That is why I brought it up. I think I may have jinxed myself and they may be warped a little. I will be paying more attention to this this week as I really don't notice it too much but I have noticed it. I don't drive very much, work is 4.5 miles away and everything else I need is within 2 miles of my house, not really enough time to get up to speeds haha.

    Best time to check for warped rotors is coming off highway speed at an off ramp.

    That’s right, I forgot you cleaned the pins and put new grease. Absolutely nothing wrong with going that route.

    You can do a test with rotors by taking a little ride and doing a hard stop or two and see if it pulses. Off-ramps from highway speed as @PNW VietVet said will surely let you know.

    If you test the rotors and don’t get any pulsing, I would check to make sure the calipers are still sliding freely. Even if you do get pulsing, I’d check them. If they are, and the cylinder looks to be in good shape, I would look hard at your brake lines.

    I would put a bad hub or suspension stuff way down on the list of suspects now with the information you have shared.

    This could pose to be a problem, nearest highway is about 45 minutes away :)

    No off-ramps within 45 minutes of me so hard stops it is haha.
    I'll plan on doing this within the next week or two.
    What stainless lines would you recommend?

    That's a relief about the hub and suspension parts.

    Thank you very much for the assistance, I really do appreciate it

    Glad to be of some help. My goal is to always be more of a help than a hinderance. :cool:

    As for stainless steel lines, I can’t recommend any as I’ve never used them. I have replaced lines but have always used whatever Autozone or NAPA had. There are others on here that have gone that route that are much more knowledgeable than I am on that topic.

    I had a very similar issue on my truck. It ended up being the brake pads. The "ears" on the pads were vibrating and rattling against the clips/brake hardware. I lubricated the brake pads ears with copper based anti seize lubricant and they were quiet for about a year. Noise came back, so I cleaned and lubricated the pad ears again. This time I also added some "anti squeal" stuff to the area where the pads contacts the caliper and the caliper pistons. No noises ever since, and that was about a year ago.

    Well, you certainly have been a help:happy160:
    I had ss lines on my 2dr but don't remember which ones I had. I'll search the site and see what I can find.


    Thanks Scotty, when I have mine apart I'll be sure to check and hit those spots with some anti seize. I'll go find some anti squeal too.
    Thanks again
