To get the absolute best out of the usage of friction in the brake (shoe linings to drum surface, that is) it's essential to remove the friction from everywhere else - the entire operating mechanism from the handlebar lever to the cable to the link rod/trunnions to the cams, etc. Les H offers some excellent advice in this regard.
My own 500 Bullet (as purchased) already had the Hitchcock trunnion mod. I found that if the upper cam was sticking in the brakeplate, which it was - (due to dried up "copper grease", as it turned out), because the top trunnion had been drilled, the lower lever and link-rod could no help push the upper lever back. It was then possible to have one shoe partially stuck "on" while the other shoe was operating normally.
After servicing the front brake I put it back to the standard set-up to prevent a recurrence, but I suspect I may be alone in doing so.
Alan R - Just re-read "Technical Notes" on front brake; our hosts don't recommend oiling nylon-lined cables either, suggesting they don't need lubrication.........
