Brake drum cracking

I know that the drum would get really hot and I would have to pull over to let it cool and the adjuster would expand the whole way which is odd and probably caused the shoes to be eaten up and the drum to get very hot.

I am sure. I would certainly endeavor to find out why. You don't want the same problem all over again. I wonder if the self adjuster is either on backwards or on the wrong side. That could cause it.
