I am not sure about anything, but that master cly looks like it's for drum brakes??

I used to work at Hader Industries here in Cincinnati, they made master cylinders and pistons. I ran a screw machine making those pistons inside the master cylinders.

Looks like this is what you have a 1 1/32" bore Drum Brake M/C. Definetly the wrong set-up for your combo.
