I agree with Greg and Dan.

I've got a seriously brake challenged car, and run Castrol SRF just for the added small bit of protection. BUT, if you are boiling a "good" (550 plus dry boiling temp) fluid like ATE, Motul or Castrol, then you have a cooling issue you need to address.

Note also that the dry boiling point is less important than the wet, according to the "experts" anyway. Most brake fluid starts to absorb water the minute you crack it open and the dry boiling point isn't really that relevant.
