Bryan,
I do realize that the standard Spridget disk brake setup is more than
adequate, but on the other hand why do some of the racers do the upgrade if
it is so adequate?
I do have a new (NOS)3/4" bore MS that I haven't installed yet because I
wasn't sure if I'd notice the difference, and if so it wouldn't be worth the
trouble... that's why I was asking the list.
I'm definitely going with the dual brake line system (converting the clutch
MC to another brake MC) and I'll be adding an 8 to 10 lb residual pressure
valve to the front disk circuit to insure they grab first. The linkage to
connect the two MC cylinders together will be the easy part, at least for
me.
Still open for advice on the BIG brake upgrade.

Drew,
I did a disk brake conversion on my bugeye, but I'm still using the later
midget
brakes, however, I do have 'cross drilled' rotors. I'm sorry I can't help
you
with the Big-brake conversion, and I wish you luck if you have your heart
set on
it, but I should add, that the standard disk brakes are much more than
adequate
on our car. The only thing that is the problem is the pedal pressure
required.
You can always add vacuum assist brake booster, if you want to reduce the
pedal
pressure, or, you could try converting to a later brake master with a
smaller
diameter. The smaller diameter will require more pedal travel, but since you
no
longer need a clutch master, you can probably fit any brake master you want
in
the existing pedal box. I also like your idea about 'dual line' brakes out
of
the orginal master, however you would need to fabricate some kind of linkage
to
actuate both pistons simultaneously from a single pedal, and that might not
be
the easiest thing to do.
