One problem related to brake foundation components has been reported for the 2004 Chevrolet Silverado. The most recently reported issues are listed below.
Brakes failed while approaching intersection causing vehicle to come to stop in the middle of intersection. Applied brakes lightly while approaching the intersection, and when appling brakes harder, to come to complete stop, they went to the floor, causing vehicle to roll into intersection before stopping almost being broadsided. My wife had the same failure on two other occasions. The vehicle was taken to the dealer for the brakes feeling spongy on two other occasions and we were told ,"the brakes are working normal" after the near accident on 6/7/05 it was taken to the dealer again and I was told by the service manager that they would bleed the brakes and that they would contact gm about the problem . The service manager told me to get rid of the truck as the brakes could not be repaired. I filed a claim with gm that evening and they got back to me on 6/10/05 saying there was nothing they would do to fix the problem.
