[TR] Silicon Brake fluid

[Jim Vassiliadis]

I intend on changing to silicon brake fluid (dot 5) and red the Buckeye tech
report on compatibility with the glycol (dot 4) based ones.
Apparently small amounts of the dot 4 will not upset the dot 5 fluid. What
is the best way to remove the dot 4 without taking the pipes off and blowing
air through them?
Also how do I bench test my Lockheed brake servo which my friend overhauled
prior to installing it on my TR?
The reason for pretesting is that I was told that even if the bore was honed
it could still have micro pitting which might cause the servo to leak fluid
back into the master cylinder.
