Brake Disc problems of the 2002 Chevrolet Silverado

I own a 2002 Chevrolet Silverado hd 2500 which was purchased new in sept. 2002. The vehicle replaced a 1989 Silverado 2500 which had 189,000 miles at the time of sale. Never did I have a brake problem with that vehicle or any other. Since the time of purchase, the brakes were very soft and the vehicle slow to stop. I attributed this to the weight of the vehicle. The antilock breaks, my first on a truck, seemed to activate more than I would expect. I regularly have the truck serviced at either the dealer or at a goodyear service center. It should be noted that either of these are quick to spot something that they can charge you to replace. The truck has slightly over 40,000 miles, almost all of which are under highway driving conditions. I commute 25 miles when I do drive it to work and that is primarily at non-rush hour times. All but the last mile is on the highway or on country roads. In other words, very little braking. At least half of the miles have been recorded on long highway trips. I rarely pull anything with the truck. Rarely has the truck carried heavy loads. Recently I noticed that the vehicle would vibrate violently when I applied the breaks. I took it to the dealer to have it checked. I was informed that all 4 rotors needed to be replaced for a cost of nearly $1,200 dollars. I have never even had to replace a pad on the brake system - the part that should wear out. The dealer and the manufacture just say that it is a maintenance item and deny a problem exists. My 10 year old car has 85,000 milesand just recently had the pads replaced and the rotors turned for the first time. In other words, this is not a driving habit related problem. As I look at consumer information on the internet, I find that I am not alone with this sort of problem. This is a factory defect that can cause death and or injury. I am currently afraid to drive the truck until something is done.

Front/rear brakes wore out prematurely. Dealership repaired the problem.
