if you have a major vaccume leak on the brake booster, you will have an EXTREMLY hard pedal.
 
Master cylinder? Are you talking about when you apply the breaks its gradually goes to the floor? You can check your booster by turing the car off and pressing the brake pedal. It should frim up each time you depress the pedal. Turn the car back on and press the pedal and the pressure should go.

what symptoms will you get if this check valve goes bad?
 
not positive, but i'm pretty sure that if that chekc vlave is bad, when you apply the brakes, you're whole vacum system will get a push from the pressure built up- so i dont know.
