<VV> Re: Brake Shoes

Smitty says:  Anyone who thinks there will be a detrimental effect from
running shoes of the same length is simply not understanding, or thinking
through the forces involved there.  If you are talking about the original
brakes which had a hard and a soft shoe with the soft shoe being shorter
it might make a noticeable difference. All you might realize from a long
secondary shoe is maybe a little more servo action from the extra area of
friction but this is offset by the reduced PSI because of the area.  I
agree that the only reason for the shorter shoe in recent years was
pretty much trying to equalize the wear rate since the short shoe is only
a servo shoe.  Most likely the reason for manufacturing them the same is
because the expense of that extra 1 1/2 inches of lining is less than
running production for two different types of shoes.
