Help with brakes please

Are you getting pressure on the rear line outlet from the prop valve? Got where this is going? Need to chase the entire hydraulic flow until you quit getting flow. It's a PITA, but better a PITA now than meeting with a more severe PITA on the road.

I had problems with a crimped rear brake line (steel) with the Demon that I uncovered trying to bleed rear brakes. A small crimp has dramatic effects on rear braking.
