I checked the clutch reservoir to see if there was any external leakage of brake fluid. There was none, the slave cylinder was in good working order. So, where is my problem? Turns out the the process of pumping the clutch pedal is a little different from my vintage cars. Pumping the clutch pedal down initially causes it to stay down. It must be pulled back up by foot at least 4-5 times, build up semi-pressure, hold the pedal down, release bleed screw, lock back in place, and resume the cylce. The brake fluid was clear and free of bubble till about the 5th cycle when I got a burst of bubbles. We kept the reservoir full and continued through another 4 cycles just for good measure. The pressure returned in full force!
Occam's Razor comes through once and again. Hope this helps someone who runs into a similar problem as I.
Also, Great Thanks to Torque for posting that awesome Bentley Service Manual PDF!!!!!
