[TR] Brake fluid for Triumph

[Randall]

All brake fluid is "synthetic", as it's not made from petroleum.  The term
is essentially just a marketing ploy; it has no real meaning in this
context.

And yes, you should always use a freshly opened bottle, then discard the
remainder.  Even their "low moisture activity" fluid still absorbs water
right from the air, meaning it starts getting old the minute you crack the
top.

Sorry, no idea if the new Castrol is the same as the old Castrol.  I'm a big
believer in DOT 5 (which, among other advantages, doesn't suck water out of
the air and hence keeps forever in an opened bottle).
