I have no doubt that heat was at the very least a contributing factor to this
failure. The aluminum got hot, expanded, and the steel band insert had room to
'grow'.
I run Carbotech's XP8 compound front and back. According to Carbotech, it's not
that aggressive, but I have always felt the compound was not very rotor or drum
friendly. Perhaps a less aggressive brake shoe compound would work OK with
these drums, but wouldn't that mean I would have to dial in more rear brake to
get the same stopping power? Will a less aggressive compound give me the same
stopping power with less heat??? I don't think so, would love to be told
otherwise...
