Air Bags

We are having an issue with our airbags deflating on the right side as it sits. As this happens the airbrake won't release. We have had a mechanic look at it and he said it didn't leak for him - it always leaks. Any thoughts anyone? We have a 2008 36MDDS.

The reason the air parking brake won't release is because the air tank is drained.

All air systems will leak down over time and if it happens over 3 or 4 days, thats acceptable.
If that's the case, you can live with it.

Since the right side is dropping, that's probably where the leak is. I would start in the rear right, air ride lines and control.

If your a DIY, get the MH up on blocks, where it won't drop on you if all the air comes out, crawl under and spray soppy water on any air connections you can see.

You may have to keep starting the engine to refill the tanks every 1/2 hour or so between searching and spraying.

If you not a DIY guy, find a new mechanic. The one you used isn't interested in fixing it.

Look closely at the air bags, they wear developing leaks.
