1987 YFM100 - Rear Brake Ring
Hello everyone. Have a question about the rear brakes on my 1987 Yamaha YFM100 Champ. When I removed the rear brake drum I later noticed a ring installed in a groove on the outside of the drum. Does anyone have any idea what this is for? It doesn't seem to have any function that I can tell. See attached pdf.
Thanks!
Thanks!
