Two problems related to air brake antilock have been reported for the 2002 GMC Sierra. The most recently reported issues are listed below.
Brake abs system is activating at low speeds. Often when I come to a stop from 5-20mph the abs system activates for no reason on dry, clean roads. Several times I've narrowly exscaped an accident. The truck doesn't want to stop at all when the abs activates.
Anti lock brakes kick in and vehicle doesn't stop!.
