After you shut the engine down,the booster should hold vaccum.Wait 5 min.then pull the vac hose to booster.There should be vaccum.Start the car up,have someone pull the vac. hose off the booster,while you are pressing on the brake pedal.The pedal should move,up or down,I cant remember which way.Then,reinstall the vac hose,again,the pedal should move,the other way. There should be a check valve on the vac. hose to the booster.Do you hear any vac. leaks,inside car?
