Brake Light On problems of the 2004 Chevrolet Astro

Antilock braking system warning lights and brake light came on when I was entering the freeway. The lights continue to come on whenever I am driving. I had it checked at corning Chevrolet and was told the part alone was $900 plus labor to replace it. The brakes work, but not the antilock system installed by the manufacturer.

It started with my abs brake light coming on and staying on. Then I started to encounter anti lock pulsations when I slowed down and coming to a stop, some times I couldn't even stop when & where I wanted. Braking distance started being longer. Then some time later I felt as though someone stuck a brick under my brake pedal because no matter how hard I press, I guarantee you, I couldn't stop. Thank god no one was in front of me as I cruised on though the stop light! I was told that my abs sensors were slowly malfunctioning most likely due to corrosion, a proven design defect. Then my abs module will get shorted, and there is no fail/safe when it goes. I was told that when the module fails, hang on because I will crash. This scares me to death and I wont let anybody drive my van in case this happens when they are driving. Also when we want to take a trip I don't want to take my van because I'm afraid 6 to 8 people could get hurt and it would be on me. Every reason I bought this awd van is completely out the window. I cant sell it because of the brake problem. I'm stuck with a van that I cant use. I'm writing this because when I went to get the abs serviced I find out that I could write a complaint about the problem ( I didn't even know you could do that ) because something about a communication problem to the abs module since 1999. And that they recalled the chevy trucks that had the same problem years ago. I would think you would fix the vans before the trucks, because trucks don't carry a lot of people! they carry wood. When ever I drive this van now, I consider it a russian roulette. I cant afford the 2200. That was estimated to fix it. I have always believed in chevy, but I cant believe that I drive afraid every day. I cant believe that chevy knows about this problem.
