Unless you have REASON to believe the thing has problems, I'd leave that
valve alone. There's not much in there to go wrong.

Silicone fluid is a waste of time; I know, I run it. You can get
the story off the net, but basically: while it doesn't eat paint
(good) or soak up so much water from the air (good) it soaks up
air (bad) costs a lot (bad) is incompatible with everything else
(bad) and all in all, all of the benefits you get from it are more
easily obtained by simply bleeding your brakes generously every
year. There are some marginal positive effects at high temperatures,
but that's old news, and there are newer, cheaper, better fluids even
better that are compatible with good old dot3.

My 63 Rambler has it; big waste. It's fine, in there, but I have
to carry around a bottle of juice in the toolkit just in case.
Plus brake bleeds now cost a lot more.
