Self adjusters keep overtighten

They are 10". I'm by no means an expert, but the springs feel tight and snug. Everything else seem to move freely. I'm gonna be replacing the brake shoes out back because of the broken of lining on the secondary shoe. So it will come apart. I'll take a good look as how the arch of the new shoes lines up with the drum.

I'll see if it makes a difference if I lay of my habit of using the parking brake when it's back together. I want to thank you all for the help and input.
