1973 Plymouth Valiant Drum Brakes Issues

Appreciate the tough love on this guys. I did check the springs and they were lose so the comment on heat doing that gives me insight atleast to why it happened.

I didn't put the wrong size of brakes on. My family consists of mechanics and i'm still learning best i can to work on my car so when i can't reach a family member i try to seek answers elsewhere before i do something serious.

The brake pads were accurate size to the old ones but i think at this point it is apparent the whole drum brake on that side maybe even the whole do need a good replacing of new parts all around. Sadly, i don't have the cash for that so small steps in getting the present problem worked out is going to have to do. This isn't a project car it's my daily driver so i need to do what i can to get mobile and pay bills/etc.

Thanks for the links to the manuals it will be handy for the next steps i will have to take. For posterity sake i'll upload photos when i get back to work on it monday and show you guys all that happened with it.
