Brake issue and I am at a total loss.
try this from an old mopar guy, get an unpainted oil squirt can, fill with brake fluid. Now attach a hose to it , start furthest away from m/c, put hose on a bleeder and loosen bleeder. pump brake fluid until no air bubbles in m/c. tighten bleeder and then remove hose. Do all 4 and you should have no air left in system. don't let can run out of fluid!
I bleed clutch systems like this also.
