Hi again. What does the manual suggest? Either you have to introduce enough turbulence to blow the air through (in either direction) or you have to set each cylinder up so that no air is trapped in each one, before you start bleeding them. You could dissasemble all your hubs, remove the top shoes, boots ,pistons, cups etc. and pour in a little brake fluid, and try and re introduce the cup with the minimal amount of air, and re- assemble. BUT! they would not have done that in production.
So you have to think about how the put them together on the assembly line.

If you have access to a pressure bleeder, try blowing the fluid back to the m/cyl with the pipe removed. I suggest you do as Terry suggested as well. Leave the other two axles clamped off and just do one. If you clamp it off as well, having tried that. Then refit the pipe to m/ cyl. You can gently bleed the bubbles out at the m cyl. by operating the pedal as you tighten the nut. See if that worked.
If it does, clamp off that one and go to the next.

What is the "plug" at the brass junction block for? Is that there to facilitate bleeding?
