Building on what Peter said:
My piston was ALL the way out and the backing pads (a la Bernie) were all

This left the piston slightly "cocked" at an angle making pushing the piston 
back in IMPOSSIBLE.  Absoulute alignment was needed.  I took the caliper out 
and used a vice.

ETKA (at least for the avant AFAIK) shows a bias Valve left and right in 
ADDITION to the front to rear bias mechanical valve under the drivers side BACK
