Re: New Worksman Drum Brake Hub - No Stopping Power
All drums take a little while to break in. The shoes need to seat, the glaze needs to wear off, etc.
Sanding the shoes and the breaking surface of the drum will help.
Also, adjust it by turning the barrel adjuster so it just barely rubs when you free spin the wheel.
Another thing that affects braking is the cable. If you have a crappy, mushy cable it squishes when you pull the brake. Get a compressionless cable like Jagwire, and that'll help.
Make sure the brake arm is solidly mounted to the fork. If it comes loose, the drum will spin, lock up, and hurt you. Badly. Trust me. I know...
