I have an 05 Tahoe Z71. The problem im having is when im coming to a stop, the abs engages. doesnt do it all the time just randomly, when applying the brakes, not standing on them. Turned the rotors, pads are decent so it shouldnt be them. Changing the hub assy, a few years back, not sure if that is the problem since the sensor is in them. Any help would be greatly appreciated.
