Subject:      brake master cylinder leak

found the location of my brake master cylinder leakage and wondering if
anybody can shed some light as to what may need to be replaced.  1980
westy.

to recap:  after a hard brake noticed brakes seemed "soft". checked
fluid and it was very low and a puddle of fluid appeared on my mat by my
feet.

took gauge cluster out, removed steering column cover.  inspecting brake
master cylinder. saw a small hole (looks like it belongs there) on the
brake master cylinder, centered between the two bolts that hold it onto
the big round black thing (vacuum boost?)  when i pump the brake pedal
hard you can see brake fluid moving in and out of this hole (doesn't
squirt out)

Qe:  is this hole a vent for one side of the booster diaphragm?  What
does fluid coming out of this hole mean?  do i replace just the brake
cylinder or the hole master cylinder/boost assembly?  Brakes feel fine
now and no further leakage, but just the same as it's been very nice
here (philly area) i've been driving my conv.

thanks
