On my 2002 Volvo S80. When I release my foot off of the brake pedal I hear a wheezing like sound like when you hold the mouth of a balloon and squeeze it slowly until the air seeps out. When I put my foot on the pedal it stops the noise. What is the problem?

There is a vacuum leak at the brake booster and you need to have it checked.

SOUNDS LIKE YOUR VACUUM BOOSTER IS LEAKING

WANT A FREE OPINION?

HAVE AN AUTO SALVAGE YARD FELLER LISTEN TO IT....THEY LIKE RECOGNITION, SO AT MINIMUM PRAISE THE FELLER, IF HIS SHOP IS INCAPABLE, OR YOU'D RATHER TAKE IT ELSEWHERE

THIS IS WHAT IT LOOKS LIKE ("EXACT FIT" IS FOR YOUR VEHICLE")
