i got fairly bored reading page three so i apologise if i repeat anything that has already been said.
a couple of issues i can think of whilst looking at this from a design point of view.
Where would a relatively sized reservoir be placed around the already tightly tucked internals of a road gear/brake lever?
how would you fit a rotor into a 130mm spaced rear end without flaring the chainstays and affecting q-factor as a result.
the other thing i'm thinking is that when riding in the hoods, the amount of pressure the user is able to exert isn't that great either so a more powerful brake would be a bonus.
I'm not a fan of the idea on a racebike as i'm a sub 11stone rider who's never had trouble in wet or dry.
the idea would have to be standardised completely in order for it to work as wheels would have to slot in, mm perfect in the case of a puncture. neutral vehicles carrying spare wheels wouldn't have to time centre a caliper.
I'm really neither for nor against the idea, i see it as possibly a little overkill but have nothing to back this up. i just don't need it.
