I adjusted the piston pushrod out a few turns just to see what it would do. The braking action is not better however the point at which the braking action occurs has become sooner in the pedal travel rather than later so this tells me I am getting full use of the stroke now as well as before since there is not a performance change.
Checked out the calipers today to see how the lack of a residual pressure valve was affecting the system. I agree it would not affect performance unless the pads we so worn that it was taking a significant amount of fluid just to get them in contact with the rotor. The new pads are pretty tight. I can barely get a piece of paper between the pad and rotor when the brakes are released. Now this is not to say that the recent pushrod adjustment has had nothing to do with that and I am sure, without the valve, I will have to occasionally re-adjust the pushrod to maintain that gap but that is not an issue right now.
Re-adjusted the rear brakes further to make sure I am not wasting too much pedal on the rears not effectively stopping.
Pulled the hose and valve off the booster and got the WOOSH so we know that is good too.
Talked to a good mechanic friend the other day about bore and stroke and with my 1-1/8" bore and identical stroke I should have great braking regardless of my stock calipers.

URE is less than a month away and I still am without brakes.
