If you didn't know there is a new TSB out for brake squeal on cars built before 3/05 (sorry I don't have the number but my dealer is the one that told me about it so it's out there) they have a new rear pad to put on
Mine squeal too. I took it in one time to get other tsb's done like the isolators in the front and the tranny slipping and they said the brakes were glazed over. So they 'deglazed' them and it still happened. I was going to take it back in soon to get the gas filler deal fixed since that is giving me problems now as well. I'm glad they finally put out a tsb on this. The squeal is horrible, especially for a new car to be doing that.
I was getting this problem too, thanks for the TSB. I need to take it in but I just hate going to the dealer because it takes fore-EVER. Anyhow, thanks.
