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

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
