I'm putting the rear wheel back in my '58 M21 but one of the parts has got me scratching my head.
67-6081 is described as a brake lever steady strap but I can't see what function it performs as, according to the parts book, one end passes through the wheel spindle and the other end over the brake cam bush on the brake plate. Any ideas?
I don't know anything about post war BSA's. But my WD Velo's have the same thing. It's simply to help stop the flexing at the brake arm pivot to eliminate the equivalent of a 'spongy' brake pedal. Ron
