I think I've always chosen brake fluid based on boiling point, even back when I was only driving on the street and buying brake fluid off the shelf at the mass-market parts stores. Brand didn't matter as long as the temperatures were among the highest available. I was an engineer for most of my career (retired, these days), so buying on specs rather than advertising always came easy.

Once I started tracking one of my other cars, I've only looked for DOT4 fluids that met more specific boiling point specs, starting with ATE200. As I got faster, I started looking at fluids with still higher boiling points, feeling that it was better to have higher temperature fluid than what might simply "suffice".


Wet bp is more important in street driving where you wouldn't be periodically bleeding the brakes (like you would before or after each track day). Dry bp would be more important for regularly bled/changed fluid in a dedicated track toy.
