Brakes failed on our 2004 Ford Focus zx5 4 door hatchback as my wife went to stop at a stop sign leaving our development and was broadsided by a truck. This resulted in a total loss of vehicle and injuries sustained to my wife. Police and medical personnel were on the scene. She was transported to hospital.
