    Hello All;

    I have been a member since 2017, and have lurked, reading all of your posts. I checked for this problem and haven't found anything like it.


    When I depress the Brake pedal, in the morning, before I start my 2016 Chevy Tahoe, SOMETIMES, not always, there is a loud high pitched squeal.

    I haven't turned the Truck on, it isn't moving. Is this part of the recall, or could it be something else?

    Regards,
    Gretchen

    Where does the noise sound like its coming from?
    Inside, underneath, under the hood etc.
    Have someone step on the brake to recreate the sound and try to pinpoint where you hear it loudest. that would be helpful in giving you a more definitive answer.

    Thanks for answering, Galante.
    To me it sounds like it is coming from under the steering column, in the inside of the truck. It doesn't happen all the time, and it doesn't happen (yet) when the truck has been driven during the day.

    First: Welcome to the forum from Oregon, Gretchen


    We recommend that you put all your rig(s) info in your signature so we all don’t have to guess at year, make, model, engine size, trans, rear axle locker…….etc. Makes it way easier on all members that attempt to help, to have that info right up front. It is also recommended that you take a pic of your RPO codes, on the inside cover of the glove box, and post that image in your signature. All this info will greatly help those that will try to help with a problem.


    If there is any other info, like upgrades, mods or recent mechanical/maintenance work done, that would be helpful in any post as well. Too many times a question is asked by the poster and after about 10 responses we find out that the poster has done recent work to attempt to fix the problem or work that was done that SEEMS not related to the problem.

    Gretchen, is the noise like a squeak...metal on metal or more like a vacuum cleaner squeal like belt is stuck or slipping?

    spray some wd-40 or some type of graphite lubricant on the mechanism down there, the brake pedal is metal and there is a hinge spray it there.

    Doesn't sound like a metal on metal. It occurs when I press the brake pedal. The noise stays the same pitch and volume and then stops. More like a belt squeal.

    Thanks, Doubeleive, I can try that, but I wonder why it is so inconsistent.
