How to tell the difference between silicon and DOT3-4, take a small drop
out of the master cylinder, and put it on some car paintwork. Leave it
for a couple of minuets, come back, if the paint is comes off, it's DOT
3-4 if not it's silicon.
There is a page I have seen, can't remember where that describes the
propertys of each, if you use this, and compair with the use your car
get's then you can workout which to use.
According to this page, I don't think silicon is recomended for racing,
or anyware where the brakes get hoter than normal road use. It's good
for a car which goes to shows etc. I would rather change MY DOT4 brake
fluid twice as often as the silicone, thus not have the risk of water
beading up in the brake system, and it will still workout cheaper, with
a higher boiling point. Water boils at 100 degrees remember, if you
have silicon an it beads up. Where as water desolved in DOT 4 is much
higher.
