2003 Ford Ranger rear brake problems

[03FX4]

Today my rear brakes on the drivers side (left) just started to make weird noises such as scraping/squealing and some slight clunkage in reverse...

This happens on right turns and alot worse sounding in reverse, and when i go over bumps it kinda squeaks.. and randomly happens when i'm braking.

Right now I'm looking for a diagram of the brake if possible so I can check it out and know somewhat of what im doing kinda. Also any suggestions of what the problem would specifically be would be cool too.

Thanks.

EDIT: Fixed

Took the drum off and a spring fell out.. that kinda sucked, but it was the spring for the brake adjuster cable.. the bracket thing on that was bent into an L shape... the spring was scraping agaist the drum causing the noise.

Bent the adjuster cable back and put the spring back and she's good as new..
