Ferrari Mailing List: Re: 328 master brake cylinder rebuild

[Rick Lindsay (rolindsay]

I just re-read Rui's note and the thing that hit me
immediately, that I hadn't seen before, is the brake
booster.  If there is a leak in the booster, the
valving or a vacuum line, the driver will experience
these kinds of pedal fluctuations.  Worth considering
before tearing a master cylinder out...
