so this is what happens when cheapo rear brake shoes wear away the inside of your brake drum - they become "lipped" which prevents drum removal, thus necessitating the use of more, um, "assertive" disassembly techniques to avoid damaging other internal components...
in this case, the use of a cutting wheel not only removed the drum, but helped illustrate the wear profile too.
anyway, don't use the $20 brake shoes folks - cough up the $40 for genuine honda and fine yourself able to actually re-use a brake drum for
300k+ miles.
