72 Duster Resurrection

For now if your just testing her out, i'd put all the drums back on if theres no evidence of leaks, power flush the lines with compressed air, bleed it, and (carefully) drive it. With it up on jacks after bleeding, have somebody press and hold the brake pedal, then go around the car and make sure each wheel thats up in the air doesnt turn with pedal depresssed. If somebodys pressing the brake pedal and you can turn a wheel or 2, then likely you have a frozen or sticking wheel cylinder at that wheel.

I recommend you do this check, and heres why.
Remember my buddy with the 68 el camino that we did the compressed air brakeline clean out i mentioned? We didnt do this check prior to a test drive, and one wheel cylinder was froze up. When he toed the brakes pretty strongly at 25 mph the car made a hard left because the right front side brake didnt grab. I had to check my pants after i punched him in the arm.
