I have a 2008 Fleetwood Diesel, on a Freightliner Chassis. On two occasions when the MH was set up for over one month, I went to move it and the brakes were stuck. I had the "rock" the MH in reverse / forward several times to get the brakes released. When they did release, they make a loud popping sound. I have not found any damage and all systems still work correctly. Has anyone else experienced this? Is there something to do before parking the MH to prevent this from happening?

I would say that humidity would be the most likely cause; brakes wet when parked, shoes rust to the drum.
You have to check and see if the " S " cam shafts are properly lubed and the auto slack adjusters are in good condition ; lubed and maintaining adjustment as per specs.
The loud popping is prbably due to the shoes , snapping back from their stuck possision and re-contacting the S cam.
Warm , dry brakes prior to parking, may help. but not always possible.

I agree with the humidity, it did rain a lot during the month it was parked. I do keep it under a cover, but still there was a lot of rain both times. Thanks for the advice I will look into the "S" cam shafts.

I've had it happen also. I put it in reverse then neutral and back to
drive and it let loose. Everything working ok. Subsequently I had
the wheels pulled to do the S cam lube, and all was ok. I suspect
the moisture issue as noted, I don't think warm up is relevant as
I always let things warm up.
