99Roo Posted July 7, 2021 Share Posted July 7, 2021 My "99 outback started to have shrill whistle coming from inside the car when pushing on the brake pedal and now it does it a lot just when driving down the road and some times gets louder when cornering. Has any one heard of this and maybe know a cause or where to look for the source?? Quote Link to comment Share on other sites More sharing options...
Jay762 Posted July 9, 2021 Share Posted July 9, 2021 Are you sure its inside and not your brake pads low metal indicator hitting the brake disc? Quote Link to comment Share on other sites More sharing options...
99Roo Posted July 9, 2021 Author Share Posted July 9, 2021 No it is not that kind of sound and it does it when the car is stopped sometimes. It sounds like maybe an air of vacuum leak and the more I think of it , it might be a vacuum leak in the brake booster. I checked the vacuum hose connection and it is solid. what makes me think that is one day after I shut the car off , it whistled and kind of ran down to nothing. I'll have to have the dealer check that booster. it is getting unnerving when it runs all the while I'm driving! thanks for the response Quote Link to comment Share on other sites More sharing options...

99Roo Posted December 22, 2021 Author Share Posted December 22, 2021 The problem was a vacuum leak in the brake booster. The dealer said the part is no longer available and could not fix it. I bought a rebuilt booster on line and had a mechanic put it in . Problems fixed!!.............Merry Christmas, Jim Quote Link to comment Share on other sites More sharing options...
