Brake noise

Wondering if anyone is experiencing the same thing when braking.  This started around 500 miles when stepping on the brake it sounds like someone is stepping down with wet shoes.(noticeably loud and annoying). Took it to the dealer and given one of those stupid lines "its a characteristic of the truck". Drove another hummer w/ 25k miles and don't hear it.  Anyone have this problem? Anything done about it?  Thanks
 
Wondering if anyone is experiencing a sound like "wet shoes" when stepping on the brakes. This has been happening since the truck hit 500 miles (currently has 6000). Dealer gave me some stupid line about "a characteristic of the truck". Sound is very loud and annoying.  Anyone else experiencing this and was anything done to correct it?  Thanks

You have a glaze build up on either the Pads or the rotors or both..The dealer should hav cleaned them up for you since you only had 500 miles on it....But go out and do some power braking  for about 10 stops and don't let the wheels stand still for longer than a few seconds since they at hot..Drive around without braking for a few miles till they cool off..this should burn the glaze off.

Thanks for that. The only thing is the noise is on the inside of the truck, down near the brake pedal.  Sound is definitely coming from the black boot/bushing thing against the firewall. Dealer told me something about a barometric pressure sensor. I didn't know these trucks could predict the weather! Definitely comes from this spot and is very loud.. The radio needs to be up in order to drown it out.  Have tried twice to get them to replace this or fix it or something but keep getting the same line..

I have no  noise coming from braking...

No noise here either.  I'd call it BS lol...

No noise on mine braking.  If it's so noticable on yours, and the dealer says it's a characteristic of the truck, make him show you another one with the same problem!

I think I have the same problem.  I have a "wet noise" coming from by break pedal since day one (4000 miles ago).  I have visually checked the entire system and no signs of leaks or loss of fluid.  It hasn't gotten worse and breaking remains solid.  It's not even really hearing it, it's almost feeling it when you push down initially on the break.  As soon as push even slightly hard on it disappears.  Definitely only happens with the first 1/4' of push.

had brake noise, dealer said that small stones caught in grooves in brakes cleaned and took glase off brakes. i asked him what is going to stop this from happing in future, no answer

I am confused but only I don't know whatr wet shoes feel like or sound like...there has to be a better discript...

The only other way I can explain the nosie is it sounds like and old man gasping for air. When you initially step on the brake it makes this "squish" sound. To me it sounds like stepping down with wet shoes, that' s the noise it makes. It does it everytime you step on the brake whether you're parked or moving. It's definitely noticeable and can be heard pretty clearly.  Again just wondering if anyone else had this problem and/or if it was corrected.

Yep! I've got that squish sound when I step on the brake. I haven't bothered to ask about it...really doesn't bother me. I usually drive with the radio on anyway.

I'm gonna ask the obvious "Your shoes aren't wet are they?"

Damn! that's what it was all along.. Problem solved...Actually the first time I took it in I got the feeling that it was a defective brake booster (or whatever it is they call it) and they knew it was a problem. The lead guy told me to take it back if it got worse.  Well it has and now the tune has changed from a problem to a "characteristic"  go figure.. Eventually I will get them to fix it by continuing to bring it in for the same problem..If you don't treat a rash it just spreads........

You should get NO Squish sounds when depressing the brakes..period..if you're told it is normal that is BS!!
 
You either have air in the system or the diaphram in the vacuum booster is making the noise..it may mean nothing is wrong other than it makes noise and that part of it, I can tell you is not normal.

Tell them that you would like that in writing, then when you have an accident they can foot the bill.

That's a good idea.  Even though what Dennis says is more than likely true, this annoyance should not be there.  Maybe if they are forced to put their reputation on the line by signing a letter saying "it's fine", even a little shred of doubt might make them just replace the cylinder/diaghram/whatever just to prevent any risk of liability! 

Believe it or not, they did put it in writing on the work order.. It says" truck characteristic".. Go figure. My brother-in-law has onas well 06' and his doesn't make the noise..

Phone GM customer service direct and fax them a copy of the WO, and make GM "admit" as well that this is a "characteristic" of the Hummer.  Tell them you know many other Hummer owners who would disagree!  Me for one!
