There is more to consider than just boiling point. DOT 4 is less hygroscopic
than DOT 3 & being less hygroscopic, absorbs less moisture from the air.
This means less corrosion & longer lasting brake hard parts.

Did you try to call & I did not answer? I apologize but I never answer
numbers I don't recognize because I'm tired of sales people trying to sell
me life insurance, health insurance, Obama insurance, merchant services,
very expensive money and the latest, greatest "guaranteed to make millions"
investment.

Subject: Break Fluid - DOT 3 vs DOT 3/4 Vs DOT 4

Dot 3  =  Boil point 280
Dot 3/4 = Boil Point 480
Dot 4  =  Boil Point 512

In looking at Brake Fluids tonight - "ol Red needs a refill - I found these
numbers.

The shelves were full of DOT 3 and 3/4 but only one little can of Dot 4
- And I wanted a 32 oz container at least.

Question: Would the Dot3/4 be safe for use in the Vanagon. I'm suspicious of
it - but there are copious amounts available. But the boil point is 32
degrees below the DOT 4.

Comments?

Thanks,

John
