We just found out we need to Drain the air on our coach periodically.
Unfortunately we have the Firestone Intelliride System. No instruction in the manual regarding the steps to take when dumping the air.

Do we turn the Intelliride system while dumping the air?

Do we release the engine brake since it is our emergency brake before dumping the air?

Thanks for your help.

Merva,

Welcome.

A little more information on why you need to "Drain the air on our coach periodically"

Is this to check for condition of the air dryer (please verify you have one in your air system) to make sure there is no water or oil in the wet tank?

If so, you do not need to drain all the air from it-- just enough to verify that you only have clean dry air coming out the drain.

And, your emergency brake/parking brake is SPRING APPLIED, AIR RELEASED. So draining the air (if you need to do it) just insures that the brake is ON.

We were told to drain the air to ensure no water or oil in it, yes. Thanks for the reply; I will pass it along to my better half.

We have a 2005 HR Scrpter. I believe we do have a dryer.

Assuming your talking about draining your 3 air tanks, you shouldn't need to worry about your air ride system. You should have check valves which prevent your air bags from emptying with your tanks.
Sometimes these fail, so don't put yourself in a position where the coach could come down on you!

Thanks. We will figure all this stuff out eventually with help from nice people like you.
Kind Regards.

Your air reliese parking brake has nothing to do with your engine brake.

One type is internal to the engine and the other is basicly a valve that blocks the engine ehxaust from coming out to the muffler.

The first type will have 2 or 3 settings, high or low......

The second type is actually called an ehxaust brake and it will use some air from your air system to close the valve, but only while your foot is off the throttle pedal and the switch is on.

Already mentioned valves to get any moisture oil from bottom of tanks. The wet tank is like drop out pot for the other two. Most rigs have a double tank, with bottom half of one is the wet tank . If a lot of water or oil in wet tank can show an issue ,with compressor ,lots of oil and lots of water a dryer issue. Some tanks have auto mechanical drains or possibly electric drains, some have pull cables or chains lastly they could just be manual valve requiring climbing under. I hope someone has actual info on what you have on your rig or shoot some pics .
