One problem related to air brake antilock has been reported for the 2000 Chevrolet C/k Pickups. The most recently reported issues are listed below.
I have owned a 2000 chevy tahoe for 3+ year and have had anti lock brake problems. The brake do not engage sometimes and almost cause me to crash and creating a damgerous situation. I am a careful driver so I alway keep the problem in mind and try to always give my self enough time to stop, but sometime in emergency when I really need the brakes they don't engage and have almost had accidents. This has been an on going problem ever since I bought the car. The brake don't engage and the vehicle keeps going even with full pressure. Most obvious when road is wet. Very scary.
