Hey Dan,
Since youre replacing the calipers and not the master cylinder it
will be
interesting to see if the spongey lever problem is solved. Rembering
that the
second part of the problem experienced is the fact air gets into the
system and
was generally thought to be the master cylinder.
I will end up doing this myself as I'm starting to get a bit tired of
having
to clean and bleed the system every 5k kms. But its always good to
compare the
experience of others.
Brett.
I have a side question here, Brett. If you think that the MC is to
blame for allowing air into the hydraulic system, then why do you keep
cleaning, lubing and rebleeding the calipers?
Your comment "Remembering that the second part of the problem

calipers seem wrong.
I mean wrong from the waste of time wrong like doing erectile tissue
repair on a patient that really needs quadruple bypass surgery.
If the problem really was the MC then all the folks that are doing the
'Busa and other brake caliper upgrades would still be complaining
about their brakes. But I can't remember seeing any of those sort of
posts, since I got here last year.
Also there really is no way that the MC could case the caliper pistons
to stick in the bores, unless the MC was not releasing properly.
This would not manifest as a spongy feeling lever, it would manifest
as a rock hard lever and dragging/smoking/glazed brakes.
