2001 Ford Taurus brakes problems

My parents were getting off of the highway and the vehicle would not stop. My dad was standing on the brake pedal with all of his strength but the car kept moving through a red light and into oncoming traffic where they were hit by several vehicles. My father had multiple serious injuries and died on august 10th of 2007 as a result of those injuries.

I lost braking when a came to a hard stop. Noticed that brake fluid dripping out by driver's door. I found out the brake lines that go to the rear of the car ruptured. Most of the brake lines are visible and are in good shape under the vehicle. Part of the brake lines rise under a recess in the underbody floor. There a plastic shield protects it from the parking brake cable. It was there that the lines had corroded badly and ruptured.
