Well I could not pry it out, but what the hell the old master is junk, I broke the piston and it seems the rod is the correct lenght.
PS Is there anything I need to put on the ball end of the rod or is it out just resting in the master bore with the pedal pressure holding it in place? Even if I lift up on the brake pedal it is OK and does not fall out. I thnk the overall length is perfect for pedal height.
