What NHTSA recorded
An axle "no brake" condition could result from an eaton controller internal electrical malfunction. This condition may cause the anti-wheel lock valve solenoid to be continuously energized and prevent the brakes from being applied on one of the axles. As a result, the anti-wheel lock warning lamp is not activated.
Remedy
The dealer will inspect and, if necessary, replace the anti-wheel lock controller without charge to owner.
