Unfortunately I have a load of labor today into my brake bleeding on my '56 F500. I have replaced every line on this truck, rebuilt every cylinder and installed a remanufactured C462C Booster. In following instructions I've found here I'm supposed to bleed the booster first. Some boosters appear to have two bleeders. Mine has one. My buddy did the brake pedal pushing while I worked the bleeder. Now the pedal is rock solid and only moves an inch. The problem: no fluid coming out of the booster bleeder. I even took the bleeder out entirely. No difference. What am I missing here?!

Sounds like the plunger stuck in the booster. Do you have the big line on the opposite side from the vacuum line vented? I have seen this happen when mud dauber wasps plug the vent line.
If you mean the atmospheric breather line that is brand new and clear. No wasps. Yet.
And do I have the vacuum lines crossed. Hmm. You may be onto something. Now I have to go over my instructions and diagrams again. If so, did I damage the booster? I've only ran the engine for a minute or two with the new vacuum lines installed. And if they were crossed, would that push the plunger in a position to block me from bleeding the booster?
My vacuum line from the engine connects to the manifold vacuum supply port on the face of the booster diaphragm housing (not on the back of the hydraulic cylinder) as shown at the absolute bottom of the below picture. Is this correct?

Booster
Sounds like you have the vacuum lines right. Are the fluid lines correct also?
You nailed it Mech/Joe. I had the line connected to the "booster" in the distribution block going to the "output" on the booster itself. The input of the booster was connected to one of the other ports. I switched them. And thanks for the graphic! I looked everywhere for that exact picture earlier!

Glad you got it figured out, sometimes the schematics for the lines are difficult to decipher.
