OK, I installed the new mater cylinder after bench bleeding the the proportion valve with the spring and green tube left out.
Couldn't bleed the rear, no fluid came out, moved to the front and they bled fine. Turned attention the the rear again and disconnect line at distribution block at rear axle, no fluid. WTF Checked pressure at exit of prop valve and have pressure.
Go figure, my new adjustable prop valve won't pass any fluid with the knob all way in or out!!!
When I get the new one I'll let everyone know the final results.
