Here’s the scenario:
Replaced an old wheel with a worn drum with one that has a drum that measures within new tolerance. Now that brake drags. We want to be sure we don’t have a swollen expander tube, can anyone help with a dial caliper measurement of the thickness of a good expander tube? The one in question measures between .230” and .237”.

Thanks!
