pull the master cylinder loose from the firewall by loosening the bolts several turns until you feel free space when moving the pedal.
If you preload the master cylinder the rear piston will not pump fluid.
Well, I loosened the nuts and also adjusted the push rod at the pedal inside to pull it in further, pumping the pedal a few times after each turn. It helped slightly, but I was only able to get a slight trickle out of the rear reservior still. Any other suggestions?
