weak /useless handbrake

[snoosebomb]

i can't say it doesn't work but it is very weak . I took the drum off to observe its operation , there is about a 1mm difference in diameter across the shoes handbrake on/off. The lever 25-26 seems to have no means of leverage except a little at the top against adjuster 21-22 . assembly seems correct as it looks like no room for error . Brake lever set for 7-8 clicks

 any ideas ???  thanks ,
