I wouldn't blame the failure on the fact you are using silicone fluid. I'm =
not saying it wasn't the cause, but regular Dot 3/4 fluid can cause the sam=
e thing. I bought a TR3 that had been sitting for a number of years and som=
etime during its hibernation, a seal in the master cylinder failed which re=
sulted in a waterfall of brake fluid and "melted" paint underneath it. At l=
east silicone fluid won't do that! I run silicone fluid in all my Triumphs =
and have never had a problem. It doesn't overheat unless you're doing lots =
of hard braking (that means racing) which doesn't happen with street cars.

You can probably repair this with a MC repair kit instead of a new MC. But =
if you decide to order new, I'm not sure Lockheed is available anymore. I b=
elieve TRW bought Lockheed and all new MC's have TRW on them. I Have one on=
 my TR6 and it works just fine.

Good luck, Joel...

My MkII Stag is the USA Stag known as "uncle jack" that was reconditioned i=
n 2009 for John Macartney's charity drive across the USA and Canada.

It has had silicone fluid in it since the rebuild.  I put it up for the win=
ter.  It had a full brake reservoir.  In the spring, the brake reservoir wa=
s empty.  The engine has not been run.  There are no signs of leaks anywher=
e.  Based on my experience with a Rover 2000TC many years ago, I assume all=
 the fluid is in the brake servo vacuum canister.

Am I correct in assuming that I will get all the parts to repair this by or=
dering a brake master cylinder?

Ought I order the Lockheed or the TRW version to have a better chance of th=
e seals playing nicely with the DOT 5 Silicone brake fluid?
