Many thanks

Hi
I don't have one, but a Google search for 'brake trunnion' shows a vast choice and they're not really expensive. If no one else is able to help, may I suggest that you measure the hole size in the arm and see what is available from other bikes?
Good luck,
George

Did you ever find a replacement for this?
Thanks - J.

I happened to buy these recently. They're sold in a general hardware store, I think for DIY furniture such as IKEA sells. With minor modifications they look like they'd work as a rear brake trunnion. I've also bought brake trunnions on eBay and agree they're fairly easy to find something that'll work even if it might need minor modifications. All the best and good luck.

Thanks for the reply ! That's handy, I searched 'M6x20mm steel barrel nuts' on Amazon and found lots of them, I might grab a few to mod.
I ended up using a modified BSA Brake Leverl Trunnion. Worked pretty good, but the OEM was a nicer fit :)
