Air Bag Not Deploy problems of the 1996 Lincoln Town Car

On four separate occasions the consumer experienced a loss of braking due to four different sections of the metal brake line due to exterior corrosion. Each time the vehicle was taken to a repair shop to have the brake line replaced. The dealer was notified. The vehicle struck the rear of a utility truck due to the brake failure. The air bag did not deploy. The first failure occurred in 2001. The brake pedal had gone to the floor upon application with no braking effect on either axle. Each failure occurred by ruptured steel brake line due to external rust.

My wife, sharon m. Davis, sustained a rear-end collision while waiting for a stoplight to change from red to green. This ocurred on 08/23/2001. Upon impact, air bags failed to deploy.

Consumer was involved in 50 mph frontal collision in which the driver air bag did not deploy, cause unknown. Please give any further details.
