Sorry, its not the check valve. The check valve keeps vacume in the booster during the time the car is shut off or when the gas pedal is to the floor. The hiss you hear is a leaking seal inside the booster. Not that big of deal to change the booster. 2 bolts to remove the brake master cylinder & resivoir from the front of the booster, be carefull and swing it off to the side (don't crack or break a line)and you won't need to bleed the brakes. 4 nuts to remove(yeah, they can be hard to get to)and the booster can be lifted out. Put it back togeather and enjoy good breaks!
