Thanks for the reply. Yeah, I thought diameter (lever length) would be a
factor, and in road racing etc I can see your point. But a 1/2" bigger
lever? Is it worth it? Wouldn't simply a 1/8" larger wheel cylinder
create enough force such that a 9" brake would be equiv. to a skinnier
10" brake? I realize that wouldn't scale up much though.
