General question regarding drum brakes, rotors, and hubs 71 valiant

Update.

Turns out I was right to do my brakes as soon as I did. I thought they were braking funny and it was pulling to the left, so that's why I started this project. Once I pulled the driver side front brakes apart I found out just how close I came to fiery death.
