You can try resetting the quadrant, but I doubt that will help. Sounds like either the clutch is dying or the cable has stretched.

Or, you could always convert to the 1994 onwards Escort design, which is to go to manual adjustment.

It was actually an option on MK4 Escorts as a TSB, if the customer complained about the clutch travel, the tech. was allowed to convert across. Saves having to mess around with those stupid quadrant things.
