Brake Master Cylinder problems of the 2006 Volkswagen Beetle

Was driving and realized my brake's didn't feel right. Had new brakes and rotors put on. . Had the brakes and the master cylinder bled. . Still felt funny. . Took it to a garage this am and he found that the booster vacuum is bad. Mechanic tried to call to order one and they are scarce. He believes the shortage may be because their is a recall on this. Also the glove compartment latch fell apart and it's impossible to find a used one anywhere because they are in demand by vw owners.
