Component: Air Brake
Manufactured by: Volvo Trucks North America Inc
Affected Units:: 771
The traction solenoid exhaust can be obstructed due to inadequate drainage and a build-up of road contamination between the mounting bracket and the solenoid housing. The obstructed exhaust prevents the relay valve control air pressure from venting after a differential braking traction event.
Dealers will remove the suspect valve and install a new valve that has a modified solenoid housing which will allow for sufficient drainage and a new valve mounting bracket with increased height to reduce entry of contamination.
System: brakes; air systems. Vehicle description: class 8 heavy duty trucks equipped with a bendix atr traction relay valve. Note: owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time, should contact Volvo gm heavy truck at 1-800-528-6586. Also contact the national highway traffic safety administration's auto safety hotline at 1-800-424-9393.
