The defect

Piston sticking in the valve can occur due to exposure to high concentrations of fluid contaminants which may collect in the braking system. As a result, no air would be delivered to the brake chambers supplied by the anti-lock valve. Lack of air to the air chambers will result in a "no brake" condition on the affected axle. This constitutes a non-compliance to federal motor vehicle safety standard no. 121, "air brake systems".

The remedy

Dealer will replace the suspect valves free of charge.
