I posted this a while ago;
UPDATE... After trying various adjustments and R&R the wheel many times I discovered that I could not get the short arm shoe to touch the drum much at all. So I put a .020 shim between the cam and the foot of the brake shoe. I could then turn the adjuster rod and get identical contact on both shoes. and about 7/8 contact on each shoe. So now I have adjustment capabilities in the adjuster rod which I didn't really have before. I think the short arm shoe showed marginal contact only because of hard braking on the road. Step 2....I cannot leave the shim in the brake plate so I will have to shave off .020 from the long arm shoe. Could not road test it this eve because of the shim but I consider this a success so far. Back at it this Saturday.
The motor started in 5 kicks..we changed the cam from a JS1 to a stock Commando cam.
NO, NO -Very DANGEROUS !
.020 SHIM AS A SLIPPER IS NOT RECOMENDED ! why it will wear down eventually and possibly jam the break on, or as it did one of my bikes broke the anchor arm, allowing the brake plate to revolve around with the wheel – don’t shoot the messenger!
I realize the bike cannot be ridden with the shim in place
further update... after measuring the linings I discovered that the long arm shoe was thicker than the short arm shoe...beyond the adjusting range. So I swapped the shoes and ended up with a little adjustment room. To make a long story short, I took it out for a ride and there was a definate improvement in braking. not 3X better but an improvement. And any better braking is worth the effort. Perhaps it will improve further with more use. no squeeks, no grabbing.
