Listers, in an early posting, it was stated that the boiling point of silicone
fluid was lower than polyglycol based brake fluids--something like 440 degrees
was mentioned. According to the Dow Corning spec sheet that I have in front
of me, the boiling point of silicone is greater than 700 degrees. This plus
no water pickup and no damage to your paint obviously makes this desirable. I
am going to put it in a Tarashchi Formula Jr. that I am restoring (with drum
brakes).
