First thing: If you or anyone reading this is a member of Club Triumph, please go to the Spit/GT6 forum thread "Rev Limit" and tell him to put an old (or new) condenser back in his distributor. Thanks.
OK, on to the brakes.
Damn. Already bought and rebuilt the Toyos. Went with the mod because of the comparison test results in VTR. Of course those were on a TR6 and the greatest improvement came after they added larger rear cylinders to the Toyos. I expect the weight bias to be even more nose heavy in the CGT, so playing with the rears after adding the Toyos may actually be the key to improved stopping (as in the TR6).
However, I'm not going to race the car, so ultimate performance isn't the goal anyway (but I've at least found ceramic pads for them). Some of the mods I'm making to the car are strickly because I think they're cool. Yup, and I'm the ONLY guy here who does dumb stuff like that (You all "know" who you are - lol).
I think I have 16Ps ('68 Mk1 GT6) not sure if there's a big difference between them and the PBs (or if I've been misinformed completely - that never happens! - lol)
I do have an after market set of aluminum 13x5.5" wheels though. The interference possibility you raise could be a concern though. I'll get to play with the brake system this weekend - we'll find out about interference soon enough.
Thanks for a great reply - I know a bit more about the system now.

: Jim,
:
: If you've got 16PB's already, think and
: read hard before you do it.
:
: I fitted the Toyota four pots (really,
: they're only "2 a side"
: pots), and I'm going to refurb the
: Girlings and go back.
:
: The cons of the Toyota calipers are:
:
: They're no lighter than the Girlings.
: Actually, mine started out slightly
: heavier.
:
: No real performance pads available
: (they're pickup callipers, and the pads
: available are pickup quality).
:
: They have a wider dimension on the
: outboard side - mine didn't rub on
: stack wheels, but sure did on my
: minilites.
:
: They have a taller dimension on the
: inside diameter. The didn't rub on
: standard hubs, but they fouled on the
: canley's alloy hubs.
:
: The pros of the Girlings are:
:
:
: You can get performance pads. Lots of
: them.
:
: You can space them and fir 2.8i Capri
: rotors if you want to fillde around.
:
: They do work.
:
: I've shaved the hell out of my 4 pots,
: and trimmed the inside of the
: minilites, but they still clip under
: heavy braked turns, so it's back to
: Girlings for me.
:
: Theres a wealth of posts about this on
: Sideways Technologies and Club Triumph.

: Hi All,
:
: I'll be fitting the Toyota four piston
: brake calipers to the
: "Franken-6" (catchy, ain't
: it?).
:
: Question: I have to assume that the
: Toyo brakes will use a bit more brake
: fluid, which will mean further pedal
: travel. Won't that cause the rear
: brakes to lock-up early and continually
: give me a differential pressure warning
: light?
:
: If anyone has the answers to these,
: please let me know of a good
: mitigation(s). (TR6 rear cylinders,
: maybe?). I'm thinking of designing a
: diagonal braking system to avoid the
: differential light problem (messy - it
: would probably make Medusa look like
: she needed a perm)
