I recently finished a Disc brake conversion on a 66 Sport Fury, installed new 73 front disc Brakes and replaced the rear drums. The system includes a new Manual Dual reservoir Master Cylinder (Replaced the old sigle Reservoir MC), all new lines, the adjustable proportioning valve controlling the rear brakes, new wheel Cylinders, new Calipers. The issue I am having is that I am not getting fluid pushed through the system, I can pump the brakes and the MC stays full, but if I remove the lines going to the master cylinder It is pushing fluid out of the ports when I pump the brake pedal, but it does not seem to be distributing the correct amount to the lines. Last night I tried gravity bleeding the system but it still doesnt seem to be dropping the amount of fluid in the MC. Any help or ideas would be appreciated.
