When braking at very slow speeds(less than 5 mph), my ABS system engages. It can be startling and the truck keeps rolling forward unless I pump the brakes to get it to stop. The truck is drivable, I just have to be careful when pulling into our garage or slowing behind someone at a traffic stop.
Any thoughts on what could be causing this?
Have someone check the wheel speed sensors for rust. What happens is rust forms under the wheel speed sensors causing the sensors to become misaligned to the speed sensor tone rings. This then causes the ABS to engage at a slow speed just before the vehicle stops.
The fix is to remove the wheel speed sensors, remove any rust from their mounting surfaces, and then apply a thin film of grease to the speed sensor mounting surfaces to prevent future rusting. Then reinstall the wheel speed sensors.
