Excessive Front Brake Drag

So went to go take a look at front brakes on our 67 cuda and realized could barely spin the rotors they were dragging so much. KH small bolt disks. Just replaced the master cylinder with the doctor dif plastic top. Did notice that cracked the bleeders it squirted out and then if I pull back on the brake pedal it lets them spin again. Does this mean the push rod is too long or is there something else need to be looking for? Also if it is the push rod is there any work arounds or do just need to get a adjustable push rod
