Brake Fluid Leak problems of the 2006 Mazda Tribute

Pulling up to place my order in a drive through with the car going idle speed when the brakes were applied I heard the front brake line blow causing my car to lose ability to stop. Underneath the brake line was a puddle of brake fluid.

The contact owns a 2006 Mazda Tribute. While attempting to parallel park, the brake pedal extended to the floor. The contact noticed brake fluid leaking underneath the vehicle. The vehicle was towed to a dealer and they stated that the brake line appeared to have been cut out. The contact stated that this was impossible. The mechanic then speculated that the brake line may have become loose on its own. The dealer replaced both front brake lines. A week later, the vehicle was not braking properly. She took the vehicle back to the dealer, but they found no failures. The following day, while driving downhill at 10 mph, the brakes failed when the pedal was depressed. She managed to stop the vehicle and noticed that all of the brake fluid had leaked out again. The vehicle was towed to the mechanic and he stated that the same failure occurred, but only to the rear brakes. Both rear brake lines were replaced at that time. Currently, the rotors need to be replaced or regrounded. The contact stated that the rotors were replaced just before the failure occurred. Mazda was unhelpful with explaining the cause of the failure. The contact believes that a recall should be issued so that the failure does not recur in two years. The failure mileage was 90,000 and current mileage was 95,000.
