I was still rolling about on my Goldwing back then figuring it would be forever before I retired and brought my Norton back to life..... Guess what? Forever isn't all that long, but I can tell you for certain it hurts and is about 35 pounds heavier for the Norty to pull around.
Have I mentioned of late how much I love that old bike?
I was wishing mine had at least had a drum up front the night I laid hard on that Lockheed handle and received a fistful of fluid shortly before reaching the end of the road.... No joy going through a chain link fence.... Might have made it with a nice sweet old fashion 'cable operated' TLS.
I've had drum brakes fade before.... I've never had them completely fail on me providing they're maintained. The rear drum is only good to keep ….. well, I've never figured what they're really good for..... keeping it from sliding around.... slowly down in a leisurely manner, mounting the sprocket, so there's something for the left foot to do, etc.... Nah, I do use it, but don't give it credit.... Just no fat stops when needed.
