Two problems related to air brake wheel speed sensor have been reported for the 1999 Chevrolet Suburban. The most recently reported issues are listed below.
I see online that the 1999 Suburban's anti lock brakes activate unexpectedly and are under investigation. I also had this problem and have repaired it in accordance with gm's technincal service bulletin on the subject. I removed the antilock sensors and cleaned the rust off of mounting surface on the front brakes and the problem subsided. The problem occurred when under 10 mph and was frequent and unexpected. On one occasion I nearly hit the fire station I work in's apparatus door and on another occasion I nearly hit a fence on the backside of my driveway.
1. When braking at low speeds, the anti-lock brakes come on. 2. My truck won't stop - I could crash into anything, worse yet - I could injure someone. 3. Nothing has been done to correct this failure yet. I'm dealing with this daily!.
