No flow. I was able to take it off completely without spilling the fluid. It’s on the bench in a vice now, I’m gonna mess with the piston position to see if it will flow water through when held very slightly pushed in (thinking maybe the pin needs to be extended). I took the rubber grommets off to make sure all the holes are lifted up. The design has the holes in slightly different positions, but all areas are still getting fluid. With this much already done, I’m giving bench bleeding another go tomorrow
