Excessive Front Brake Drag

Oh my GAWD. Everybody tries to make this harder than it is. Here's what you do. Duplicate the condition where the front brakes are locked or dragging. Now. UNBOLT the master cylinder from the firewall leaving EVERYTHING still connected. Brake pushrod, brake lines....EVERYTHING. Then try to turn the front wheels. If they turn, the pushrod is too long for that master cylinder. This is a REAL common issue changing from one master cylinder to another, OR when replacing a master cylinder with someone's reman as they all have a little different tolerances. REAL simple to figure out in less than five minutes. I don't know why these guys try to complicate it all to hell and back.
