Almost have the drum brakes done but have a question.

You can't go by that diagram because you have the wrong cable setup. Look closely at the adjuster lever in the diagram and you will see that there is no spring at the end of the cable, just a hook which goes in the eyelet of the lever, which is also incorrect for your application. You need the closed eyelet, the hook ended spring, and the counter spring that tensions the lever against the cable.

If you just try to use the cable/spring you have, there is no counter tension to keep the lever in place!!

Hope this helps clear up your dilemma,Geof
