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!?!? :)

~~ mutter ~~

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.

Vacuum brakes too and as points to introduce anti freeze into air
lines on trailers.
