I have been a fan of silicone DOT5 brake fluid for over 10 years now.
I have it in my Austin A40 which was restored in 1996.
I did replace the fluid once in those 10 years and it was clean, no water, no paint peeling, and I have had only 1 hydraulic failure in all those years, it was the clutch slave.
I am running it in my 58 and 59 Sprites also. The 59 is pushing 5 years since it's restoration and no problems with any hydraulics.
The only side effect with silicone is that it EATS the pressure type brake light switches. I even ordered special silicone fluid brake light switches and they lasted about a month like the $2 switches did. So if you go to silicone, figure out a mechanical brake light switch if you have a pre 68 Spridget. My 58 Sprite which has been on the road since Valentines day has already gone thru 2 pressure switches.
I want to keep that car original looking so I have not yet come up with a mechanical brake light switch.
