[Healeys] Brake Fluid

[Bob Spidell]

I've had silicone in my BJ8 for over 30 years and 150K miles, and DoT4 
in my BN2 for 15 or so years and just a few hundred miles (my dad put in 
in after a total system overhaul). The silicone has never caused a 
problem that I can attribute to it, but the DoT4 gelled once after the 
car sat for a couple years and recently one of the slave cylinders 
sprung a leak. Note the DoT4 that caused the problems wasn't Castrol.

IMO, either is fine, but you should flush and replace the DoT4 every few 
years. Silicone is available, but somewhat harder to source.
