Hi Bruce
SS 3 leading shoe brakes are actually quite easy to adjust, despite what everyone says.
Firstly, papajam is 100% right, check that nothing is leaking / loose or worn out. Assuming that all is 100% and it's just adjustment, here is an easy way to do it.
Get someone behind the wheel, front end jacked up & both wheels off. slacken all adjusters 100% off - till they jam on the pins - remember when you are facing a front drum, with a spanner on the adjuster nut behind the drum, to slacken off the adjusters, to follow the direction of the wheel backwards, is to slacken & forwards is tighten. (tighten anti-clockwise on LHS - Sinistro and tighten clockwise on the RHS - Destro). Remember, this is when you are facing each drum.
Now tighten up each adjuster, one click at a time, alternating between the 3 adjusters, till the shoes just make contact, BUT, the trick is to have someone pump the pedal each time you have adjusted the 3 adjusters once each. This settles the 3 shoes into position as they are floating shoes & each click on the adjuster of an adjacent shoe affects the other 2 shoes. Otherwise it's the same principal as adjusting the 2 shoe Normale & Veloce drums.
It's a bit time consuming, but works like a treat.
Shout if you come unstuck, I've got a brake rebuild doc I can email you as well. This includes how to rebuild the whole system.
