When it gets really cold here in milwaukee, my brakes make this air hissing sound when applied for the first few minutes of operation. I ran a search and came up with nothing here...
Whats going on here??
I have NEVER heard about this on any other cars.
Oh, found something out here, there could be a chance that snow had gotten onto your brake lines somewhere, and then melted, and when it froze back up, it damaged the brake line, and so, when you apply pressure, the hissing sound is made.
Ok first off, I want to thank you guys for replying to my post, but #1 I do not believe it is worn pads because it only happens when it is really really cold.
#2 The line isnt damaged bc like I stated before they work fine on a daily basis, but until they get warm (10 mins) they make noise.
The sound actually comes from inside the car, below the dash....
it sounds like someone is taking an air hose and blowing air. This has to be the wierdest thing that has ever happened in my car as of yet.
Probably noise from your brake booster. My 95 Intrepid does that sometimes. I have never had a problem from it. If you are worried, check the large vacuum line that goes to the brake booster and make sure it is not old and rotten or bad in anyway. If you are unsure, replace the rubber hose. That is my experience.
That ususally happens to me when the car is parked overnite, where IMO water condensation/rust formed a bit on the braking disc?! So when you brake, it kinda scrap off the rust.
I'm quite sure it's rust, coz once I parked it outside for a few rainy days... where the front brake disc kinda turned orange. But it looks normal again after applying a few brake while the car is moving.
If you haven't tried already, next time it happens (and you don't need to be moving) apply the brakes several times in a row with only a second or two in between applications. Do the same thing when it gets warm and see if there is any difference.
My 99 Es is doing the same thing, is your brake pedal hard as a rok at that time, i talked with my local dealer i know the owner and they had 4 people call with the same problem they are saying the brake boosters are getting moisture in them and freezing , anyone else hear he samething
This is my response i got back from Dodge I think everyone having this problem should e-mail them and let them know they have a problem that should be dealt with a Dealer wants almost $400.00 dollars just for the booster-Dear James,
