Phil,
Irrespective of whether the late TR6 caliper has metric hydraulic threads,
the caliper-end fitting on the hard pipe is not compatable with the Toyota
caliper. One must either use a longer flex hose with appropriate ends or
fabricate a new hard line with the TR fitting on one end (the end that goes
to the flex hose) and an ISO metric bubble flare on the other end (the end
that goes to the Toyota caliper).

Subject: RE: Toyota caliper upgrade
I guess I should have been a bit more specific in my question. There is a
short pipe which connects the flex hose to the caliper on a TR6. On early
cars, like mine, the caliper end of this pipe is fitted with "imperial" or
SAE threads. Later cars had metric calipers, and metric fittings on this
pipe. My question is: Will the metric thread from a late TR6 pipe mate with
the Toyota caliper? If it does, no fabrication is required. If it does not,
then the pipe will have to be custom-made, as described in the article.
