96 sunfire n 96 cavalier brake problems?

on my cars they both hav the same brakeing system
on the passenger side rear brake keeps locking up on both cars
everytime i adust it back it overtightens it self can anyone tell me what i should do?"

Do you do a lot of driving/stopping in reverse? If so the adjusters will do this

yea i know if u go in reverse it will tighten up on its own wen u stop in rev. but no not really i replaced the drum on the other side cause it warped
