If your master cylinder is leaking through the brake booster you should 
replace it,then check the diaphram in the booster as brake fluid is
corrosive.You are sucking the fluid through the seal of the M/C through
the booster into the intake manifold which in turn pushes it through the 
engine with the fuel.Because of brake fluids corrosive nature this can
cause long term damage to the internals of an engine.This is especially
important if the vehicle sits for a long time,as the brake fluid has
time to start working on any metal it comes into contact with.  
I learned this the hard way on my 76 SII,cost me a good 345.
Some auto parts stores can get a complete m/c,brakebooster assembly from
one of the local rebuilders for a fair price,this can be an option to
look into.
