I'm working on restoring a set of Pentagram wheels for an XS650 project. They came off an XS500 and that bike seems to have been converted from drum to disc.
I have all the stuff to swap in a disc brake swing arm, but the more I look at this stuff, the more it appears I could use it with my drum brake swing arm with very little effort.
What master cylinder is this? Are rebuild kits available? What is the green thing/stuff that seems to have come loose inside the plunger mechanism? The only markings on it are "7/8", which I guess means it has a 7/8" bore.
If I can make this work, I think I will. Simply for the "weird" factor, if nothing else. Plus, I can keep the drum brake swing arm set up if I ever want to switch back.
