Hi Mike but you appear to be selling something (I missed the original post)
I assume a rear caliper setup for Triumph.
Let me know where the original posting appears as I might be interested.
However I do have a couple of comments about your later posting:

The results are approximately a 10% reduction in braking distance - actually
provides better performance than a 4 pot front caliper setup. By the way the
brake cylinders are from a Morgan.

Any idea on how much improvement this provides with regard to braking
distance or deceleration?

I'm not certain I agree with the statement "only do the Toyota calipers"
results in an "unbalanced system". I assume you are talking about front
wheel lockup prior to rear lockup. The braking capacity of the rear drums is
very dependant on adjustment, it is easy to get a stock setup "unbalanced".
I believe that John Lye races with front Toyota and stock rear (however I
could be mistaken).

Any idea on how much improvement this provides with regard to braking
distance or deceleration? I believe that all of the systems discuss "work"
in that they stop the car. The question is how well they do it without
locking up.
I've found that the TR6 is very forgiving with regard to changes in the
braking system. Remember that Triumph changed the rear cylinders on the TR6
from 0.7 to 0.75 (a 15 % change in cross sectional area) in the middle of
the production run without changing the master cylinder. You tell me which
system was "unbalanced".
Thanks for the opportunity to share my opinions with the group.
Later
