I'm going to be redoing my brakes soon, and am planning on flushing the fluid and putting all fresh stuff in. I'm looking for opinions of whether to use DOT 4 or DOT 5 fluid. I think i remember reading that DOT 4 absorbs water and has a higher boiling point, and DOT 5 does not absorb water but has a lower boiling point? Is this correct. Please educate me if you know what you are talking about.

Thanks.

Dot 5.1 synthetic.
Does not absorb water, high heat absorbtion and boiling point.

Because it doesn't absorb, you'll need to change it more often.

I prefer to go with a synthetic DOT 4. Boiling points in the DOT 5 range, but with the compatibility to use either DOT 3 or DOT 4 fluid in a clutch.
