I have a tandem with a drag brake in the hub of the back wheel. It works perfectly, providing a steady drag when descending.
QUESTION: Can I simply treat it like a normal rear wheel with cups/cones, and adjust the axle, or do I have to be careful of the drum brake's innards?
Details:
ABOVE: Drive side of axle - there is 4.5 mm of thread exposed, plus 1.5 mm of cambered slope.
ABOVE: Left side of axle, showing barely 1mm of axle through the nut and the visible bit is not threadded.
Left side view - showing drum brake arm and reaction arm.
I wish to fit this trailer hitch, which goes on the left side of the rear wheel axle. It is 3 mm thick plate.
