There is no dirt from the last time I checked the brake pads. From the last time when I took the pads off I noticed there was a clip type on the brake pad. Is that for anything?

Just because you dont see any dirt doesnt mean that there is any. I dont know that the clip on yours is for, I havent put brakes on a TB yet but I have dont alot of brake jobs on others.

Ok i have spoke with a chevy technician about the brakes. He said that the brake pad sensor (tab from what I said before) which is what is making the squeaking noise. My question which I should have asked the chevy tech is can you adjust the sensor?

I figured out my issue... The shim on the back driver side brake pad was gone. No wonder why I am getting the noise I am hearing. Does anyone know of brake pads that wont need shims?

During very very high humidity I get a squeak on the first and second brake attempts. My pads seems well within spec.

If I drag the brakes lightly for about 1.5 seconds it ends the squeak. Only happens on high humidity. Dew just dripping like crazy off the paint.

I should knock my tires off and take a good look. On other vehicles I had, it would just make them sensitive until they were applied once or twice.

Anyone else live where its 90%+ humidity all night long?

USUALLY when the brakes squeek when you do this, its just because of the type of pads you put on...when you start hearing the noise all the time thats when your down to the metal warning clip(if you or the person doing it reinstalled them)....they do make a gel type thing that you can put on to quiet them but if it really bothers you(it would me) just go buy good pads for the front and replace them....the noise isnt going away because of the way the pads wore down...it puts like an edge on them and thats the noise you are hearing


NOW THIS IS JUST USUAL SITUATIONS....YOU STILL NEED TO CHECK THEM TO MAKE SURE!!!

i have high humidity here and mine only make noise for a second if the vehicle has sat longer than a day...but it goes away before i even leave my neighborhood and its not even loud or really noticeable if you have the radio on even on very low

im getting a squeek thats getting to me too. I jsut replaced my rotors and pads about a month ago and just last week it started squeeking... most of the time it does it at lower speed. Was just the drivers side and now i think its both sides. I got a higher quality set of napa ceramic pads ($60) and a sort of midgrade rotor from advance autoparts. I used plenty of the "squeek lube" on the back of the pads.. any ideas? Could a bad set of rotors cause it?

did u use a lot of brake clean while and after to make sure u cleaned off all the rotors and pads? try it again....also if the pads weren't "burnt in" before you installed them and u didn't then that's the reason and you might be able to burn them now as long as u haven't already made a normal wear pattern

Yes I used a lot of brake cleaner. I did noticed that my driver side rear brake pad is missing a anti vibrating clip well missing half of it. Does anyone know where I can buy one at?

I have this same issue, just replaced my back pads 1K miles ago, dut I don't remember there being any of those shims in the back pads. I'll pull off my tires and check all 4 brakes and maybe clean the rotors and pads as well. Will let everyone know if it works.
