Air Brake Wheel Speed Sensor problems of the 2001 Chevrolet 1500

The brakes on the t ruck are not right. They work okay but when you are going about 5 miles per hour and hit the brake, the abs comes on makes a grating noise that you can both feel and hear. I have had everything checked and this is what is the problem. When this problem occurs it takes longer to stop than normal. The noisie is also kind of scary. I have had to put new rotors on the f ront of the t ruck and both rotors and pads on the back. All of them were rusted and pitted. The truck only has about 26,000 miles on it and it doesn't get hard use.

At about 55,900 miles, the abs on my pickup truck began comming on at about 5 to 8 mph when braking on dry pavement. This increased stopping distance when braking and led to my wife crashing into a steel pole barrier in a parking lot and destroying the front bumper.
