Re: New Worksman Drum Brake Hub - No Stopping Power
It sounds like your brake is incorrectly adjusted. You need a brake lever with longer reach than a road style handle, so that you may pull the lever far enough to lock up your brake.
Adjust your lever to the maximum tension allowed where it does not slow down the wheel. I built a 700c bike with this brake (90mm) and used a reverse lever made for road bikes. With a bit of adjustment I had it *almost* locking with the short throw, and later just added a hole up on the arm to get the full range.
