Rumors were, back in the old days, that something in DOT3
brake fluid ate the live rubber seals that LBCs use. I have
never seen any evidence of this. You are right about mixing
DOT5 (Silicone) and any other fluid. Don't, repeat don't
do it.

This is due to the use of sulfur based materials in the
early versions of GL5. I have spoken to Castrol engineers
a couple of times at trade shows and they assure me that
the latest (1996 on) versions of their GL5 lubes have
eliminated the sulfur additives.
