73 duster front brakes locking up when coming to a stop.

Thanks... It looks like somebody put new brake lines at the master. Cylinder down to the proportioning. Maybe they got the lines wrong. I need to see a diagram
i'll take: was a drum brake car didn't replace the distribution block/prop valve or got the plumbing wrong for $500 alex

but the rear brakes bobo'd up like that to work is just hack *** work. so i'd be SUS AF about everything else in the system. you're likely dealing with more than one issue, so know that going into it.
