First did vyou replace or rebuild the master cyl. If you did not or if you rebuilt it there is a tiny hole in the rear port in the reservoir into the cyl. If this hole is plugged up it will cause problems. If you have a new master cyl. disregard this. If not poke a tag wire through it. The push rod should be adjusted so it has just a tiny bit of play before it starts pushing the piston. You can tell best from underneath. Adjust each adjuater on each wheel till you get a heavy drag & back it off about 4 notches. Remember all the adjusters are right hand threads. When these brakes are right the pedal barely goes down. You just apply pressure to it.
