Dr. DIFF cobra brake/ master cylinder question

I run the DoctorDiff 13” cobra style brake kit on my Duster. I also run DoctorDiff’s 15/16” master cylinder with it, works great. I personally wouldn’t run anything larger than a 1” bore master with them, but that’s just me. I’ve run that master cylinder with both drums and now with 11.7” rear disks.

The proper procedure for bleeding the brake is to go from the passenger rear to the drivers rear, then the passengers front and finally the driver front brake. That should reset the factory prop valve.
