BSA Brake drum
Rear brake drum, PN 68-6116, for cable-operated drum rear brakes.
This is a rear brake drum, PN 68-6116, showing up in the rear wheel section of the parts books across 1969 and 1970. It's the drum-brake era part, meaning it works with a cable-operated shoe assembly rather than any hydraulic setup.

The drum is the rotating piece pressed or bolted into the rear wheel hub that the brake shoes press against when you apply the rear brake. It takes the wear over time and is worth checking for scoring or being out of round if your rear brake feels grabby or inconsistent.
Our catalog record ties this to a BSA listing, so if you're working on a Triumph, double check this is the right number for your hub before ordering. Call the shop and we'll help confirm fitment.
