B18 mystery brake lever?

[daveysprocket]

Hello again, another mystery regarding the B18 front brake. Yesterday I took apart the front brake lever and noticed the integral serrated ratchet teeth, there was no pawl to locate with the teeth. Could anyone explain what this was for, maybe a parking brake? There is a hole in the mounting assembly adjacent to the teeth position.
Many thanks
Kind regards.

A picture would be helpful.

Hi Dave,

The serrated part is for a sidecar brake lock. It is a spring loaded device: pull in and lock manually, pull in and it unlocks automatically. It was used on all mid 30s BSA with the combination levers. It isn't particularly useful on a B18 unless you lean it against a wall.

Kind regards,
Leon

Thank you Leon - I would never have guessed that.
And, sorry I will have to learn how to do photos.
