Welcome, I don't think anybody will burn you to the ground for asking questions

Inbetween all the iron on this pic below you can see a rusty piece of round metal, it actually has two small bearings inside and sits on a very small axle.
I was planning on putting the extra brakepedal for the hack on it, have not gotten round to that

It's on a r 90/6 as well

Hope it helps a little, depends on cable or hydraulic brake too of course.

The way have hooked the brake up on BMW air heads and both Velorex and the Sputnik sidecars we use to import was to make a bracket that bolted onto the final drive of the bike to hold the housing for the brake cable. This was easy on the Sputnik sidecars as they came with a bracket that was very easy to modify. The bracket will need to go onto two of the studs that hold the final drive to the swing arm. This will hold the housing.
Then to pull on the cable we take a tread coupler, (looks like a really long nut) drill a hole in the side of it such that it can then slide over the brake rod for the rear brake on the bike. Then we take a bolt with a washer on it put it into the end of a chain that is only 3 links long. Then it we add a second washer such that now there is a washer on both sides of the end ling of the chain. We then run the bolt into the thread couple such that when it is tight it pinches the brake rod keeping it from moving. The other end of the chain the hook from the Velorex brake cable goes into. You can then adjust the brake by moving the thread coupler. The chain makes it so that if any thing were ever to bind up on the sidecar end of things the brake would still work on the rear of the bike. It is also a way to make a hook fit on a bolt. In the case of the Spuntik sidecars the cable had a hoop on the end so the chain is not needed.
