I had a 92 with the dual plate set up and the travel was high and only about an inch of travel on the pedal, an almost binary feel.
This is a common thing for 348 clutches: they engage quite high on the pedal travel and over a short distance of travel.
Even after I rebuilt mine and had the system completeley bled, it was the same.
edit: sorry I'm not answering the question. have you checked the brake fluid in your reservoir?
