I installed the Toyota 4 Runner 4 piston calipers on my TR6 a couple of
years ago and I like them although they do require increased brake pedal
pressure which I don't mind. The mounting holes do need to be enlarged which
I did with a few licks of a rat tailed file (don't you just love low tech)
and of course the pipe to the brake hose has to be rethreaded. Another thing
that some people over look is that the center of the Toyota brake caliper is
offset from that of the original Triumph units. I used a 1/8" thick flat
washer between the caliper and the mounting plate (2 washers required per
side). Crank everthing down tight. If you don't center the calipers so the
pads are spaced evenly on both side of the rotor you will eat up one pad
fast or even have the piston hydraulics blow out.

Here is the info on the vented rotors:
* **Vented Toyota Brake Parts:** *
Rotors - Aimco 3247: 1986-1988 Toyota Cressida Front Rotor (Sedan Only)
Alternate Part Numbers;Raybestos 96042, Bendix 141410
Calipers - C8554, C8555: 1988-mid 1989 Toyota 4-Runner, 4WD, 4Cyl Alternate
Part Numbers: , 19-826 and 27
Looking at the dimensions of the Cressida rotor vs the TR rotor, it looks
like the Cressida rotor needs its inner hole opened up 3mm (from 76mm to
79mm) to mount on the TR hub. Diameter is very close, as the TR rotor is
276mm diameter, while the Cressida rotor is 271mm. I could not find any info
about the mounting holes for the rotor, other than they both use 4 holes.
Later note from Hugh Barber
The vented Toyota conversion uses a 1986-1988 Toyota Cressida Sedan front
rotor (Raybestos # 96042) with the inner hole bored out to the dimension of
the stock TR6 rotor and calipers from a 1988-mid 1989 4 cylinder Toyota
4Runner. Cardone numbers for these calipers are 19-827 and 19-826. As I do
not believe that the GT6 uses the same rotor as the TR6, the Cressida rotor
would not be a fit for the GT6 (you would need to use a different rotor). As
above, don't know if the caliper would fit the GT6 13" wheel.
