    front brake master cylinder

    Hi, I am restoring a 1978 GS750C, to riding condition, hopefully. The problem I am having, is the front brake master cylinder. The one that came on it was from an earlier model, that was shot. I got another one from e-bay for the correct year, but it was missing some parts. There is a large washer looking part that is no longer available in the bottom of the brake fluid resivor. It is held in place by two screws. Can I just put a couple of screws with flat washer on them to hold the cup in place?

      That washer shows up in the parts fiche, have you contacted your local dealer?

      I'm sure you could adapt a proper size washer

        Yes, you are correct, Big T, but the part is no longer avaiable, has been dicontinued. Thats why I was asking, can I just use a couple of screws and flat washer to hold the brake fluid reseivor cup in place? I could probably, come up with a large flat washer and drill a couple of holes for the screws if it were necessary.
