Ever had self adjusting brakes overtighten?

I’ve ordered brake shoes, flexible rear brake line, and new spring & hardware kit for rear brakes. Also ordered a vacuum kit to assist brake bleeding. Already have new master brake cylinder, front brake shoes and new wheel cylinders for front brakes. Rear brake cylinders were just replaced. I’ll do all of this at once and be extra careful to get springs installed correctly this time. I think I’ll disable the automatic adjusters for now and consider them later.
with all the problems you've had, I would suggest you make changes on a minimal scale, so you can treat problems logically, and as they crop up and not muddy the waters by wholesale changes.
