Brake Hoses, Lines/piping, And Fittings problems of the 2000 Chevrolet K1500

I went to move my truck from my driveway to the street. As I was leaving the driveway I had to push as hard as I could to get the truck to stop. I was able to stop the truck only when the brake pedal was as far as I could push it down. I drove it around the block to see if the brakes would work better. I still had to push down all the way and it look a long time to stop. I was not conformable driving much over 10 mph. When I got back to the driveway I noticed a line of fluid. I looked at the rear drive side wheel well and there was brake fluid all over it. It appears the brake line to rusted through.

Driving in a normal situation, braking to get over into turn lane and the brakes went right to the floor. Found brake lines under left front of cab rusted through causing complete braking system to lose pressure. Fortunately I was not in a critical situation because I lost all braking power, very scary.

During the annual safety inspection the dealer advised me that all of the brake lines would need to be replaced before the next inspection due to rust ($1200), and the rear brake backing plates would also need to be replaced due to rust. The rear brake backing plates were already replaced once due to rust-through. This vehicle has been routinely maintained and commercially washed throughout its life, driven on a daily basis up (until the last 5 months) only in eastern PA, DE, MD area (no snow belt travel). In my 40 years of vehicle ownership, I have never experienced or even heard of brake backing plates rusting through during the life of a 12 year old vehicle (let alone twice) and, have never experienced (or heard of) all brake lines on a vehicle rusting through to the point where they all need to be replaced. This is not normal wear or deterioration. It is most definitely a vehicle safety issue to have critical safety (brake) components rusting through at a highly accelerated rate for no apparent reason to the driver/owner.
