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 |

Warren, I've had similar thoughts to reduce maintenance on the fleet but ultimately resolved to use DOT 4 and just monitor the moisture in the fluid with a simple tester. They are available through amazon for about $10. This has given me peace of mind that I'm not neglecting the brake system on little used cars without needing to change the fluid every year. .
I saw Ed on Wheeler Dealers use this one time and it got me motivated to investigate. So far so good. The tester confirmed my gut feeel on which cars had marginal fluid and which should still be fresh. Brake fluid tester |
