rear brake pin

As with everything Norton, there are several arrangements.  What model is it for?

The pin that stops the pedal sliding back off its shaft is drilled and carries a grease nipple. Visible here.

The adjuster should be a wing nut.  NOC spares sells one threaded 1/4" x 26, but it should be 9/32" if the rod is correct.  (The one in my picture still has temporary hex nut.)  Originally there was no cross bar (trunnion).  That came during the War.

Hi Beverley ,

I think the pin in question is known as a clevis pin. Searching on Google throws up all diameters and length of clevis pin.

The jargon is half the battle when enquiring from spares specialists.

Use some drills to get one that fits the hole. That gives you the diameter you need. Allow for at least one washer between the securing split pin through the clevis pin hole and the brake pedal.

Hope you get sorted.
