James,

I'll add one thing...after _one_ of the many times I had my brake
hydraulics apart, I had a problem with soft pedal feel.   Centralizing the
PDWA, running the car a few miles, THEN bleeding the brakes again, released
whatever air was trapped in the system, and returned my brakes to normal.

Before doing the above, I had pumped about a gallon of LMA through the
system to no avail.

One leading question that Jim forgot was:   did you bench-bleed the Master
Cylinder before installation?
