Please see the attached pics. I have a question I hope someone can answer. I purchased a master cylinder rebuild kit from Casco (see Rebuild Kit picture), and it has a part in it that I don’t recognize to be like one I took out of the master cylinder when I took it apart (see Original Parts picture). Does the part that is circled in the Rebuild Kit picture go into the cylinder bore in front of the valve that is attached to the spring (see Mystery Part pic)? I think it shows this to be the case in the Assembly Diagram pic, but I'm not sure why you would put what appears to be a valve in front of another valve. None of the other kits sold at Mac's or Larry's show this part...
