How do I change my brakes?

My dad knows how to do all the stuff on our cars, but he is stummped on my 98 Plymouth breeze's brakes in the back.
My wheel cylinder went out about a month ago and he replace that and my shoes and drums and everything...thought everything was alright, well it started smoking and he wasn't sure why, well i burnt up another wheel cylinder and it appeared that my brakes locked up too, just on the rear drivers side. Well he just got done replacing another wheel cylinder and drums and shoes ($110 later) and well i took the car out, and it started smoking so i turned right around and went back home so i wouldn't do any damage and have to spend another $110 to get new parts. I also replace the emergency brake adjuster too. Im not sure whats going on but any help would be greatly appreciated!
Any ideas on what might be the problem? Did he miss something? Anyone have like something i could print out and give to him on how to replace the brakes in the back?
