Just finished removing/lubing/replacing the clutch cable and lever on my '75 CB550F. Figured I'd lube the lever on the right side, too. When I removed the nut from the pivot bolt at the brake lever/MC, this little doohickey fell to the floor.
Forgive me if this is a trivial line of questioning, but... What is it? What does it do? It looks like it may have held in place a "bumper" of sorts to soften the return of the brake lever? This little cylindrical rubber bumper has deteriorated beyond recognition/usefulness. Will I miss it?
