REAR BRAKE CAM 53-68 TRI
Rear brake cam for the quickly-detachable rear wheel drum brake, PN 37-1083 (aka W1083).
This is the rear brake cam for the quickly-detachable rear wheel setup, part number 37-1083, also known under the older W1083 stamping. It's the piece inside the rear hub that the brake lever acts on — when you pull the rear brake, this cam pivots and pushes the shoes out against the drum. Catalog listings for this cam run from the mid-1950s into the late 1960s, and it shows up specifically in the quickly-detachable rear wheel figures, so it's tied to that style of hub rather than a fixed rear wheel.

This is a drum-brake, cable-operated part — no hydraulics involved, consistent with the era it comes from. Later factory records show this number was superseded by 37-3592, so if you're cross-checking parts books from different years, both numbers point at the same physical piece of hardware.
When ordering, have your hub and wheel setup confirmed against the quickly-detachable rear wheel figures — that's the wheel type this cam belongs to, and it's worth double-checking before you buy since QD hubs and fixed hubs use different internals.
