hello-BArefoot site says there are 3 bands(reverse,fwd(hi and lo),brake). So when the driver brake pedals he wears lining and band. Baerfoot then says:brake band has most wear,reverse the least. So band replacement is least when using reverse to stop. I guess he means replace all 3 all together. Does not say anything about different thickness of bands. Is he right? Another question, when using a low throttle setting to slow, should the driver depress left pedal all the way?
