Air Bag Not Deploy Problems of Audi S4

1) car is 2001 Audi S4 avant. Car was running for approximately 15 minutes, and was idling at top of driveway for about 5 minutes with parking brake engaged while other car in front was being moved. Upon release of parking brake regular brakes failed, resulting in car rolling downhill, about 30 feet, from a standing start and colliding with a parked car. Brake pedal showed no resistance other than mild spring push-back, and was pushed down to floor. A brake pedal was pumped with no result.

Finally, after approximately 5 minutes following the accident brakes resumed full and normal functioning. Car was idling throughout this time period without interruption.
