It sounds like your rear brakes have automatically adjusted them selves too tight. Not uncommon with many modern vehicles; The Crown Victoria features 4 wheel disc brakes, but, these wheels have small brake shoes & a brake drum, to take care of parking brake and road side servicing ( flat tires, etc.,) any reputable mechanic, or brake shop can probably re adjust them for a
nominal fee, I hope I responded in time to save you some money with this.
