I never opened the bleeders when I compressed the rear calipers.

Dave,

With all due respect, the bleeder needs to be open no matter what 
condition the brake system.  It is a LOT harder to force fluid back up 
the lines to the master cyl than the other way.  Plus the rear brakes 
have the restriction of the bias valve.

I know that my brake systems are in good condition and yet, if I don't 
open the bleeder, it takes nearly forever to get the piston back in 
compared to opening the bleeder.

There is no reason NOT to open the bleeder, first it makes the job much 
easier, and second it won't introduce air into the system.  IF you can 
do the job in about a minute with the bleeder closed I can do it in 10 
seconds with it open.

That piston will just freewheel if it feels resistance.  Why fight the 
battle when it can be so much easier?
