When I push on the brake pedal its fine and seems to work well. However, when i let off the pedal there is a loud "sucking sound" like maybe a vacuum leak. I've been told (by no-one that knew how to fix it) that it's an easy fix. I'm very mechanically inclined and do most of my own auto work. Can you please give me some direction? THANKS!

Check the brake hose and the booster itself if its leaking
