I don't have air brakes, but is it possible that you have moisture in your air lines that is freezing? Just thinking.

Freezing weather it started doing it in?

It could also be the air pressure sensor. I don't know where it would be located on the newmar. A lot of the monaco coaches have it just below the parking brake pull actuator. Some freightliner chassis have it along the rear frame rail driver side.

Pressure is good on gauge. I drained air tanks.

Could be something as simple as the governor that controls the compressor or a massive leak.

Do NOT attempt to drive until this is resolved. As I am sure you are aware, if PSI drops below 30, the emergency/parking brake WILL deploy.

First step is to listen for a leak. If that is not it, replace the governor-- should not be over $25.

Sure, it could be something more expensive, but start with the cheap and easy.

What does the pressure gauge read? Do you have a major leak or a compressor failure?
