If you want to prevent this kind of episode in the future, apply anti-seize compound to the flange before installing the drum. "Paint" on a layer of anti-seize and install the drum, and just back off the shoes and pull it off next time. I do the same on the back faces of alloy wheels because of the dissimilar metals and potential erosion issues. My wife accuses me of putting anti-seize on my pancakes. I have to admit, the little sparkles floating in the maple syrup are pretty cool...
