I'm going thru the same thing with my '96. A rebuilt and then a new master, new calipers, rotors, pads up front, new drums, shoes, cylinders, springs out back, proper sequence of bleeding (numerous times), vacuum and 'pump the pedal' methods, bench and in the car bled the master, and still the pedal is spongy. As far as I can tell, the booster is fine, and it's not the effort, but the length of travel that I cannot seem to cure. Yeah, the linings need to be broken in, but I don't want do go too far until I fix the length of travel issue. Tonight, I turned out the actuator rod a half a turn, tightened it up a little, but I went down this road 20 years ago, only to end up seizing the brakes. No fun! Any thoughts would be greatly appreciated.....Ray
