Unfortunately, the pads that have been discarded tell the story.....it could be the proportional valve assembly keeping pressure on the system causing the calipers to drag...of if the pads are glazed, she's impersonating Mario and needs to allow more time to stop....quite common female trait....bring that puppy in for a landing at 65mph at the red light, then bind 'em up to stop!
FYI- glazing or glassing of the pads indicates HARD stopping, more than once....continual stopping like this will warp the rotors by superheating them beyond their ability to shed the heat load......
