[Mgs] brake fluid

I use Dot 5 since 2000 and found, that regular replacement must be done,
eventhough Dot 5 does not mix with water.
Water vapour still comes into the system, so finally can create rust into
the cylinder bores.
So I had to replace the clutch MC, as the cylinder bore was pitted.

   Silicone separates quite visibly.

DOT3, 4 and 5.1 aka Super DOT4 are all glycol based and hence compatible, so
you can just flush the old out when filling with the new. DOT5 is the odd
one out being silicone and the two types must not be mixed, switching
between these is not a trivial task.  I've never been able to understand why
a development of glycol was given the designation DOT5.1, implying it was a
development of silicone, and not DOT6.  Water mixes pretty-well instantly
with glycol based, never had silicone to try.
