AIR BRAKES WON'T RELEASE

2004 Monaco Diplomat.
We returned from our annual snowbird trip to Florida on March 10. Parked the coach in the driveway.

On April 2, I was going to put it into storage but the air brakes would not release. I tried several times to brake, then release.
Air pressure was good. I tried forward and then reverse. But it would not move.

This happened several times. So I gave up for a while and tried again. Suddenly, it worked.
thing seems fine now, but I need to know what caused this, and what to do the next time.

    Often, moisture will allow the drum to seize to the brake shoes. Gentle application of throttle in D, then R will free them up.

    Applying the brakes enough to warm them up before storing will lessen the likelihood of this occurring.

    What was the temperature when you tried to release them? If it was cold, there could be moisture in the system that froze. Was it one wheel or all that wouldn't release?
