Brake pedal squeak

[totalpackage]

So several months my 2010 Tahoe brake pedal squeaks when I press the brake. I’ve gotten under and lubricated what I can see. Even around that boot but still cannot fix it. The noise is driving me nuts. Anybody had this?

Try this ..

Yeah, but mine squeaked from the upper hinge point. Cured it with some penetrating Teflon lube.

 

[OR VietVet]

Yes, like @Bill 1960 and @k1970 says, use a lubricant and anywhere the pedal pivots, attaches or moves-lube that area. Where the master cylinder rod attaches. But the noise may be coming from the master cylinder itself.

Thanks guys, since posting that I had tried wd40 and Houdini. Must have gone under it 5 times to find other angles. It stopped weeks later…assuming the lubricants made it where it needed to get to.
It was driving me nuts!
