NO, NO -Very DANGEROUS !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.
Re "Ferodo are the worst for undersize shoes" Ferodo sill do or did supply OVERSIZE brake shoe linings only to recognised Ferodo supplies . . . . . This was how Joe Dunphy and others were able to rivet them to shoes and then skim them down to fit the brake drum.'I have had my brakes relined with oversized brake shoes which were then skimmed down to fit the drum by Joe Dunphy a total of 4 times (8 wheel drums) - because I was sick of buying brake shoes over the counter that apparently were nowhere near fitting the Norton brake drum diameter - it was well worth the money then , but is expensive now."
I do that to ALL my brakes I sell. Ferodo are the worst for undersize shoes.
