My chain is near new, as are the shoes. There is more than an inch the axle can move forward.
Yet the brake adjust ment barrel and nut is nearly at the end of its travel...more than 4 inches has been used to get the back brake to come on.
The only improment I can think of is make my own brake actuater that does not have it end so close to the bike.
Have I missed something? Is there something I can do?

if it’s the rear brake they are usually pretty good. Two thoughts:
have you got the correct rod fitted? And
does the actuator arm need to be moved around on the square of the cam?
It is possible to buy a new actuator arm which has a star cut out rather than the original square cutout so as to give greater finesse in positioning it on the cam, that might help.

Exactly the same as Stu mentioned. On my high mileage D14 I had to replace the arm and build up the square on the cam so new arm fitted snugly. Didn`t have the luxury of the later multi-splined arm though. You can see Mike`s is good and tight. The pivot pin that the rod passes through can become wibbly-wobbly(workshop tech term), too. I`ve never lost the rear brake on a Bantam, but there`s a few things that could fail completely with excess wear/age.
