I know this topic has been pretty inactive, but wanted to thank you all! I had been hearing this noise and finally got around to looking it up -- I googled the phrase "brake pedal fart sound" and it brought me right here. Found out about the TSB, called the dealership, and they said bring it in and took care of it, no charge. Thanks for helping me get this taken care of!

 

Mine does this off and on. Does not seem to effect anything. Only does it on occasion. H
