this is interesting.... any explanation as to why? i have the fluid i previously mentioned- silicone hydraulic/DOT5 replacement in heavy equipment- i several 57/8 and 51 with pressure switch... havent had a failed switch yet- but will be something to keep an eye on i suppose...
perhaps due to the better pressure transfer- under extended hard braking it may collapse the diaphragm effect of the switch mechanism...
the other running silicone are already converted to dual masters/discs, or were factory equipped with mechanical switches...
and somehow out of a fleet of 38 cars i can tell you what fluid is in which and when i put it in!

If you decide to use silicone then install a mechanical BL switch behind the brake petal.
