Ifg you are vlosing a lot of fluid you should see it leaking out
somewhere. Is it leaking out of the slave cylinders. Is the carpet
below the brake master cylinder (inside the car) wet with fliud. If you
can see no signs of leaking fliud, then the only place that it can be
going is into the vacuum cylinder of the brake booster (servo). An
indication of this (sometimes) os excessive smoke from the exhaust on
starting up, when a little of the fiuld gets sucked into the engine.
This is not all that rare on an old unit and calls for a rebuild or
replacement.
