In owners' own words
Failure of abs module caused abs light and red service brake lights to come on. Replacing both front hub bearings (including both front abs sensors and wiring) and repairing the ground strap on the frame for the abs system did not fix the problem. Service brake system has new calipers ,rotors,and pads and a full inspection revealed no problems or failures. Abs module is still on vehicle but will be replaced next.

Antilock brake system- very difficult to stop truck at low speeds. No accidents, but near accidents, and no injuries. Right front wheel speed sensors were replaced on 10/29/2003 and the left front wheel speed sensors were replaced on 10/08/2004. Both were replaced after the 36,000 mile warranty expired. Repeated failures of the truck bracking system to stop in sufficient time before panic set in! Service brakes, hydraulic · reported at 37,000 miles
