'73 Swinger brake drag

Assuming you have the right proportioning valve on there, can you post a picture? If the car was originally drum/drum it would have come with a distribution block, not a prop valve.

I believe this is the proportioning valve, right?

It’s also possible that the master cylinder isn’t right, and it has a residual valve in the port for the front disks. If that’s the case, the residual pressure will cause the disks to drag and the residual valve must be removed. You can do that by just threading a drywall screw into the port and pulling it back out, you should pull a small rubber seal with it. There’s a picture somewhere I’ll try to find and post.

I appreciate the reply! I'll take a look into the residual valve when I get the chance.
