Hi Les,
It seems what you are calling the 'cast iron thingy' is what's
collectively known as the brake cylinder. This would include
the bleed screw, internal piston and rubber sealing parts.
The housing is cast aluminum (at least mine are) and passes
through the hole in the brake backplate. You can buy rebuild
kits for the brake cyls, but a whole new cylinder assembly is
cheap compared to the hassle of trying to rebuild your old one.

The rubber parts are toast. Buy a new cylinder, you'll be glad
you did.
