help hard break pedal weak breaks after swap

could the rear drums be adjusted up to high even thou theirs no drag on them causing pedal to be up high and not having enuff pedal travel >mechanical leverage<
causing the rear shoes to be slammed against drums before my front are really even working if so i would think they would lock up and i have no signs of rear drums adjusted to tight no dipping in the rear grabbey effects or any thing

NO

Only thing shoes "too tight" might cause would be rubbing so hard they generate heat while driving, glaze and "heat fade" the lining.
