It shouldn't. It's not hard to check, you should be able to blow through it towards the intake but not the other way. The valve I am talking about is inside the booster. In this picture, it's called an 'atmospheric vacuum port'. If the booster diaphragm has a small split, when you push the brake pedal the atmospheric port opens and this creates a vacuum leak.
