DOT 5 Silicone fluid does not enhance in any way the braking effectiveness of your system. It is a fluid and simply transfers motion. You could actually use water, oil, or even grapefruit juice to do the same job but it goes without saying the ancillary problems would be significant.
Trust me, you don't want to use grapefruit juice. The pulp causes havoc in the brake system!
Oh, no problem. Go to the market and get the "without pulp" type juice. It costs more but then you won't have the pulp plugging everything.
Your car would be fine with Silicone living in the Blue Grass state or any state for that matter. Go for it!
