Air system maintenance
Well I finally got around to trying to pull the lanyards on the air tank automatic moister ejectors. I understand they are automatic but the owners manual states to pull them every 6 months no matter ...

Did you have the air system completely air up when you pulled the lanyards. Possible all tanks were not aired up. I don't think the auto mositure ejector is part of the tank drain valve but is the air dyer completely different than tank drain valves. Like Brett said the drain valves are report card on the air dyer to see it's doing its job.
I made sure the tanks blew off so they were full with the engine running. One had no issue. The other had a problem.
Here is what is stated.
Freightliner chassis are equipped, as standard equipment, with a heated automatic moisture ejector on the wet tank in addition to one built into the air dryer. This eliminates the need to climb under the coach to drain air and water from the tanks daily. You still must pull all three drain lanyards for 10 to 15 seconds every 6 months to drain moisture. A fine mist is normal due to condensation. If a large amount of moisture is present it should be completely drained and the air dryer serviced. Moisture in the braking system can cause brake system failure and is not covered by the manufacturer warranty.
The lanyards are attached to these ejectors / dryer. So as I found out one is not allowing air out as it should, meaning there is probably a problem with the ejector/ dryer.
