NEW BRAKES....DOT 5?

I have been doing some thinking...

We know how bad that can turn out.

Dot 3,4,5.1 are hygroscopic, dot 5 is not.

Assuming there is no air in the system all of the surfaces are fully coated with dot 5 fluid.

Condensation occures where there is a junction between cold and less cold with moisture present. ( Here in CO the inside humidity is 30 percent, and when it gets below 20 deg out side I get frost on the inside of my house in places)

My gut says if I took a glass full of ice cold water and placed in into a container of either dot 3 or dot 5 there would not be any moisture buildup on the surface exposed to the fluid.

Now leave the containers of fluid open to a damp environment for a few months and redo the experiment. Then I would expect moisture to collect on the dot 3, but not on the dot 5.

My reasoning. There is nothing in the dot 5 pulling moisture into the fluid or container. The dot 3 is constantly pulling moisture from the air into the fluid.

If nothing is pulling moisture into the fluid, no moisture would be in the container or fluid.

Personally dot 5 is growing on me.
