no m ore loads than a shorter lever arm,unless of course the brake shoes are glazed like glass and the rider simply panic grips the control lever,because the brake wont generate any heat.that is all a friction brake is is a very efficient machine to convert kinectic into heat by the process of friction
if a brake is working efficiently making bookoo heat and if it has decent feel then a longer lever arm simply means less effort at the control lever
now the thickness of the brake plate itself makes no difference either many have been just sheet metal
with the shoe cam journals,axle boss, stay locations and dead stops all inclusive in a bar stock,cast,forged or billet fabrication tying all together to handle the loading with no flex,this is what enables the feel,besides a sturdy control cable lever assembly and correct adjustment which i have outlined in other posts
on the units here the dead stop for the shoes is a seperate bolt in piece ,is it not ?
and bolted in ,in a poor manner as well,to a thin lonely area of cast without any thought of even spreading out the huge bending loads the dead stop sees
see if the dead stop is allowed to bend a bit flexing the casting it is attached to
well then it will also attempt to pursuade the shoe into less than full contact ,which then requires more lever pull from the rider and the "cure" was longer actuation levers down below
poor dumb bastards lol
so in conclusion its the dead stops
major flexing there because the mfg does not understand design ,it what cause the cast material which cannot for all practical purposes ,withstand continous flexing,to fail in the same way
all a rider can hope for is to be thrown clear lol
