It's not pot metal, it's aluminum. The galvanic reaction between the
dissimilar metals pretty much 'weld' the pieces together. Sometimes
brute force can get them apart.
If the inner bore is at all scored or pitted, you'll not get the unit
to properly seal even with a rebuild kit. If that's the case, you
can get the unit resleeved or buy a new unit. Either option is
way more cheaper than what happens when the rebuild fails and
you lose your brakes :-(.
