when depressing brake pedal sounds like a vacuum leak?
I need some help guys?I just noticed while car is idling with the hood up and the door open on my 03 cobra, I can hear a hissing or vacuum leak while applying the brakes(car is parked in garage).The harder I push the pedal the louder the hissing.The brake fluid level is good and the pedal feels normal? Has anybody else noticed this on their cobra? With the hood shut and door closed you can't hear the noise.Thanks for the help in advance!
