I suspect this a generic problem not a " subaru isse " . Anyway.......my daughters 97 Legacy L 2.2 ABS four wheel disc. Pedal has alot of travel to it before braking is effective. It is not spongy - no air etc....just takes a bit more travel than I like. I never had such an issue with 4 wheel discs........What is the move here? Nothing to adjust is there ?
Purge all the old fluid and start fresh. Braided steel brake lines in place of the rubber lines will harden up the pedal also.
Turn the rod that goes in the master cylinder to adjust the pedal engagement height. You'll have to loosen a lock nut first.
I have no idea why Subaru ships their cars with such a low pedal engagement.
