Yes, the bore of the cylinder looks to be 1 1/8" from your first photo. The piece in the second photo, however is not the piston. You can see the piston in the first photo, it's located in the bore and has an indentation where the push rod goes. I also see what looks like elongated mounting holes with thread marks on the cylinder. Did it come this way? Also, IIRC, the pedal ratio should be closer to 6 to 1. That would definitely help with stopping.
