Air brakes

Can someone point out where the release valve is located to get rid of excess moisture in the air systems?
I have always read about the importance of making sure thereis no moisture in the air system but for the life of me cant locate any release valve.
I have a 98 U320 with the M11.
Pictures would be great!

In front of the left rear tire at the bulkhead. Look underneath

And, since your coach has an AIR DRYER (in engine compartment) if you ever get anything but clean dry air, you are way past due for air dryer service.  And, if you see white powder (air dryer desiccant has broken down) it has gone so long that it will cost you many "coach bucks".

There should also be drain vales on your brake tanks and your HWH tank in the front end of the coach.  Mine are on the bottom of the tanks but your U320 may have them mounted so you don't have to crawl under the coach to check them.

Thanks to all for the information and pictures...thank God for this site...
My air dryer was just serviced in the fall so that is taken care of.
As far as OTHER air release points the one in front of the rear left tire for air brakes is the most important for me.

Yes, that is the WET TANK drain-- all air for all the systems goes through it.  So, it is the "report card" for condition of the air dryer.
