Self adjusters keep overtighten
Arrows drawn on one of your pics. Nothing about this adjust paw looks right to me. Where it rides in the hole, what is holding the cable and spring in it , spot looks grinded on ?
The half moon shaped cable guides are supposed to have little necks on them that hold them in the proper location ( when held there while that spring is placed on the upper post before the other return spring ). If that cable guide is low the cable runs long. But the pic suggests that cable is short. Then a push pin from wheel cylinder appears to be running upwards. Darned if I know. Good luck with it.
