I looked into this a while back, did the conversion, never liked the extra
pedal travel, I think maybe there is a 70s or 89s Jag MC with a slightly
larger bore that works.

I did the Toyota caliper and larger rear wheel cylinder conversion on my =

=E2=80=9CTriumph Tap=E2=80=9D method of braking. I give a little tap on =
the brake pedal before fully apply the brakes, which gave me a less =
travel on the pedal. It got to be such a habit that I had to learn to =
stop doing it when driving the race car because it=E2=80=99s a detriment =
when heel/toe braking.=20

Most of the pedal travel seemed to be in =E2=80=9Cwaking up=E2=80=9D the =
caliper pistons as they tended to spread a bit from some flex in the =
whole wheel/caliper/rotor system. It was more apparent when auto =
crossing as that system got flexed a lot more than normal driving. I got =
used to it and never bothered with a larger brake MC.
