Even some of the modern 2 terminal switches seem to have problems with silicone fluid.
Probably the only sure way to eliminate hydraulic switch problems with silicone fluid is to use a mechanical switch actuated by the pedal arm. A bracket made from heavy sheet metal -- 10 ga or so -- and mounted to the steering column with a hose clamp or the like makes the switch relatively easy to install on 56 power brake cars. A bit more work and different bracket dimensions is needed on the 52-55 power brakes because of the different pedal and placement. A 3 wire loom extension can be made to extend the wiring from the mechanical switch out to the original brake switch location and plug into the old brake switch plug on the factory loom.
Manual brakes would need a switch that goes under the car and is actuated by the under floor linkage. All three have been done on Packards and as far as I know all have worked well with no problem installations.
