general problems of the 2002 Chevrolet C1500

I own two 2002 gm products, a tahoe and a silverado pickup. The emergency brakes do not work on either vehicle. I have had to take both to the dealer for repair to get them to pass state inspection. I have contacted five of my friends that own 2002 gm products and three out of the five have the same problem. That is a safety concern and someone needs to investigate this in greater detail.

Although the truck is rated to tow 9000 lbs the parking brake will not hold my 7000 pound trailer from rolling down the hill forwards or backwards. My 3000 lb boat rolls backwards into the water at a boat launch. The pbrake pedal goes to the floor with little resistance. Two different chevy dealers have seen the truck. The first dealer adjusted the brake and it was better, the second said that there was nothing more that they could do. It still rolls with a trailer on it. The dealers said that the low resistance pbrake is a design feature.
