I've used DOT 5 since the seventies. Used in Top Fuel bikes, Land Speed Bikes, Road Race bikes and many cars. It's in my Vette now. No matter how hard I drive it, the brakes are always firm and stop great. I've never had a problem with DOT 5.

I been DOT 5 for some 15? years now, since I bought the car, a SCCA buddy was using it in his race car....my '72 had stainless lined calipers on it already, so I rebuilt it all since they leaked....lip seals with no springs, and DOT 5 worked for about 2 years, then started leaking again...went O ring pistons/seals....lasted about 5 years or so with DOT 5, street driven daily...a few years ago I replaced the O rings but today with Hydroboost, the brakes are fine....if you have a soft pedal, the problem is in the booster....assuming you don't have air, and if you have O rings, you have no air problems...unless you are a idiot...
so DOT 5 don't suck up water naturally like the others do...
no rust...
can't say about boiling points since I don't race, but have done some goodly high speed stopping, and not so awful evil....ie, nothing noticed....

Because DOT 5 won't absorb the water in the system, it will allow it to pool in remote areas and possibly worsen corrosion problems! Instead of being absorbed by the entire volume of fluid, it will sit in concentrated spots and destroy calipers and compnents of your brake system. I have observed this first hand.
