BOLT BRAKE PEDAL PIVOT
Rear brake pedal pivot bolt, 21-2045, listed for the BSA A65 (1971-1972) and Triumph 250 TR25W, 650 Unit, and 750 Twin (1971-1974).
This is the pivot bolt for the rear brake pedal, part number 21-2045, also listed as S2045 in older references. It's the bolt the brake pedal swings on where it mounts to the frame, and it shows up in the parts books under both the footrest fittings figure and the brake pedal and footrests figure.

Our parts books tie this bolt to a spread of models: on the BSA side it's listed for the BSA A65 in 1971 and 1972, and on the Triumph side it's listed for the Triumph 250 TR25W and the Triumph 650 Unit and the Triumph 750 Twin, 1971 through 1974. If you're chasing this down for a rear brake pedal that's developed play or won't pivot cleanly, this is the bolt to check.
It's a plain mechanical fastener, so wear here usually shows up as sloppiness in the pedal action rather than anything dramatic. Worth a look any time the rear brake pedal feels loose at the mount.
