DEFECT #2 - SERVICE BRAKES, AIR:SUPPLY:HOSES, LINES/PIPING, AND FITTINGS
Posted on: 1995-09-27
Description
Air system blockage in the air dryer occurs degrading the moisture removing capabilities of the dryer when the vehicle is operated in a cold environment and moisture accumulates and freezes in the air dryer or in the line between the dryer and the air system reservoir. The air dryer can become overpressurized causing the air dryer cartridge to separate from the mounting base.
Consequence
If the air dryer separates from the base, the cartridgecan separate sufficiently enough to cause personal injury or property damage.
Corrective Action
Dealers will equip air systems with a pressure relief valve to be located between the compressor and the air dryer. This pressure relief valve is intended to vent if excessive pressure develops in the air dryer.
Notes
System: brakes; air dryer.vehicle description: heavy duty class 8 trucks equipped with rockwell wabco system saver 1000 air dryer.note: if your vehicle is presented to an authorized dealer on an agreed upon service date and the remedy is not provided free of charge within a reasonable time, contact volvo gm heavy truck corporation at 1-910-279-2000.also contact the national highway traffic safety administration's auto safety hotline at 1-800-424-9393.

DEFECT #4 - SERVICE BRAKES, AIR
Posted on: 1996-06-11
Description
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.
Consequence
This condition would keep the rear axle service brakes applied without any brake pedal movement by the driver increasing the risk of a vehicle accident.
Corrective Action
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.
Notes
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.
