Quote: It sounds to me as though you are trying to use the drum brake master cylinder with the disc brake setup. If that's the case I think you need a disc brake master cylinder.
I'm pretty sure this is a disk master cylinder (I can post a pic of the setup if necessary) - back some years ago when I first found out that my drums were probably not the original setup I had posted a pic of my MC/booster set up, I was told by board members that my current combo setup is actually for disk brakes. So I'm pretty sure I've got a correct disk MC.
