If your anti-lock brakes engage at low speed for no reason, this is a possible fix. The problem comes from rust forming between the abs wheel sensor and the wheel bearing assembly. The rust causes the sensor to move slightly out of it’s hole. Even though it’s only a few thousands of an inch, it throws off the wheel sensor at low speed. You can read it with a scanner if you have access to one. Just compare your low speed readings (usually under 15 mph)to your speedometer to determine which one is off. The best part is it cost nothing but a little time to correct. Spray the area down with good penetrating oil the day before. Remove the allen screw that holds the sensor in, carefully work the sensor out with a turning back and forth pulling motion, clean, and replace. Don’t let any debris fall into the bearing while you have the sensor out.
I have fixed a 2003 Silvarado 2500Hd, a 2006 Pontiac Torrent, and a G350 Cube van with no issues so far. It does help if you can determine which sensor is wacked, but if you didn’t have the scanner you could probably clean them all.
