COVID boredom maybe... I was reading an article on DOT 5 silicone fluids that mentions a wet boiling point of a certain brand. The article also mentions, which I knew, that silicone brake fluid does not readily absorb or mix with water. I also know of folks w/ classic cars that have had issues with water settling in parts of the brake system when using DOT 5 fluid.
My question is how can the Silicone fluid have a wet boiling point greater than water? Seems to me the effective and important wet point would be the temp it takes to get that un mixed slug of water to boil. Does the test add water to the fluid then test the fluid (with some minute amount of water that will be suspended), but not what settles out? Did some web research and couldn't come up w/ a definitive answer, so I'm going to the collective BITOG brain trust
I have never used DOT 5 fluid and so have limited experience.
