Emergency brake for 9" Ford
On a 56 Ford pickup I swapped a 9" in and later added the Versailles rear disks.
The 56 cable was fine I just had to make a braket to hold the sheathing the needed distance from the lever.
If you do have the Versailles brakes there
Is a tool you will need to screw the piston back into the bore and a Ford procedure to follow. Or you will break parts or not be able to put new pads on.
