silicone hydraulic fluid, why not DOT5 silicone? Options

[worn]

We run silicone brake fluid in our LBCs (Little British Cars) and this is widely accepted among that crowd. This week I am putting new front wheel cylinders in the 47 Dodge P.U. truck cause we don't run it enough and they pitted.

So why not use the silicone fluid in a 914? Yes, there is a slight compression you can feel in the pedal, but in my TR6 you can hardly feel it. I now have enough toys so that routine maintenance is a pretty big chore. Keeping up with batteries and tires is bad enough. Yes, I know that you should bleed out the old fluid, but frankly I doubt that would have helped me with the truck. The problem was the lack of movement of the seals over the cylinder. My time flies!

So - what do you think?

Thanks,
Warren

Mine has DOT5 in it. Previous owner wanted the convenience of not having to flush/bleed system every year. For how the car was being used, it was likely the better solution.

That said, it can be difficult to bleed, is not compatible with Dot4 or Dot3 and for those who track their cars, DOT5 is usually not recommended or allowed.
