TR-4A: First problem, leaking brake master cylinder.

[John Cowan <jfcowan@earthlink.net>]

The brake master cylinder on the new TR-4A is leaking moderately.  It's the
perfect project for me:  on top of the car; self-contained; and I
understand how it works.  I'm trying to decide whether to buy a new
cylinder from TRF or get a rebuild kit and fix the old one.  Unless others
strongly demur, I'm inclined to rebuild and have a brake shop hone the
cylinder.

In any case, is there any way to tell what kind of fluid I have in there now?

Thanks.

John
