[Mgs] Where does the brake fluid go?

[Barney Gaylord]

Keep driving and keep an eye on it (and carry some brake fluid with 
you).  If it continues to be a problem, pinch off the vacuum hose 
with a coupe bits of wood and a clamp, and drive with manual brakes 
for a while (no power boost).  If that curtails the loss of fluid, 
you have isolated the problem (and the booster needs a rebuild).
