Help please with Sturmey front hub brake
I have a set of used Sturmey Archer front and rear hub brakes that I am going to get spoked up to some new alloy Pashley 28” Westwood rims to go on my very old BSA frame c. 1920s
I guess the hubs are 70s or 80s, I think off a tandem. 110mm front brake.
I am all fine with the rear hub, but not sure how to anchor the brake cable housing on the front hub. Picture attached. There is a bracket but I think it is for the rear...not sure.
Can anyone tell me what I’m missing?
thanks

Yeah the bracket is for the rear. It looks like you have a model that relies on a hook on the frame for some reason?
I have an older rear hub here that looks similar and also lacks a hook.
On a different model they solved it by using a special bolt that would secure the arm and offer a cable stop at the same time.
Modern hubs solve this by using a built in cable stop hook.
You need something like a HSL702 to secure the arm to the frame (check the sizing, they offer different diameters).
Use a fulcrum clip to act as a cable stop.

Thanks Jacob
I may have partly answered my own original question...I found this heritage diagram in Sturmey archives which appears the same but has part 21a instead of a plain bolt. I actually have part 21a in a plastic packet, so must have bought it at some forgotten point, but when I try to undo the plain bolt on my hub, it spins but doesn’t undo.

Remove the axle screw and you can lift the entire brake assembly in one piece. You can use a wrench on the inside and one on the outside to undo it.

I found this old chart on Sheldon Brown, seems there were various ways of fixing the brake cable back in the 40s/50s. My hub seems newer than that, no model or dare stamp, so I don’t know what part I really need.
