I have installed the master along with your disc brake conversion. The pedal travel is fine but brakes do not engage until about 1/2" before it hits the floor. The master has been properly bench bled by your techs and myself. There is no air in the lines. The car originally had power brakes so the pedal rod is in the proper location. Booster rod to master is properly adjusted. I have tried everything and cannot get the pedal to come up. Please help.

Thank you
