Gotcha on the block of wood.

The pedal is stopping halfway down (which indicates normal operation) however no matter how hard I stand on the pedal, no lockup and longer stopping distance. The initial bite is as it should be. The car stops just fine in traffic situations, but when jumping on the pedal at ~30 MPH, nothing locks up and the car comes to a stop with no drama, albeit in much more distance than it should.

Pedal doesn't not pump up

Pedal "bottoms out"(better description than "stops halfway down") in all braking situations

Adj prop valve fully open (full flow to rear)

I've got to think there is more air in there, but I've bled bled bled and pumping the pedal doesn't change the system behavior.
