The whole brake system (lines, shoes, disks and proportioning valve) was/were replaced Paterson, La. All except these two lines from the MC. Same time as we dropped the two fuel tanks and coated them.

We just got home from a GMCSS rally and brakes are still fine. Will
be at the Dixielander /Blue Angels rally in two weeks if any of you
interested. Oh, and I love the Yogi (isms).
