I finally got the actuator modified back to original and installed -
all set to bleed the brakes and get 'er back on the road.

NNNNNOOOOOOOOO!!!!!!

The freakin' zerks on the BRAND NEW CALIPERS were rusted to nubs -
NUBS - nothing to grip, came apart in my hands and the brake wrench.

Now I gotta remove the calipers, use an easy out to get the rest of
the zerks out of the calipers....

WHAT NEXT!?!? *:)

I am curious as to the zerks on your calipers. What are they for?

Bleeding the brake lines?

Via a zerk fitting? My trailer's calipers have "bleed screws."

Seems to me that I recall cars in the past having zerk type bleed screws on
the brake systems.
They were used because a vacuum pump was attached to them to evacuate all
the air
in new brake lines.

Yes Richard. some use pump to extract the air out of the system, but
there's the old two man way of pumping up the master cylinder, while
another opens the "zerk to let the fluid and air splatter out, until
they get a clean flow of fluid. But instead of making a big mess, it's
possible to put a rubber hose ove the "zerk" and let the air and fluid
mixture splatter into a jar or can. press the master cylinder pedal,
open the 'zerk', splatter, close the 'zerk' let up on the pedal and
repeat the process.

Done it many a time.
