Sine you've been having mushy brake pedal with all of your cars (I'm assuming during your daily drive) after only slamming few times on the brakes (surprised you din't put that brake pedal through the floor... cough..cough) just use Castrol SRF - DOT 4 - 590ºF (310ºC) / 518ºF (270ºC)
, if that doesn't help, then you're SOL until a special brand comes out for your heavy brake pedal foot. While you're at it also upgrade to StopTech or Brembo GT at least 6 pitson front and 4 piston rear BBK.
BTW I'm interested how often you change your brake pads and rotors... hmmm every 10K miles...
