My toilet uses air. It has its own 12V compressor that can be utilized if the main air supply is not available. I don't have an air pocket door but I would think Newell would supply air from the 12V compressor for that as well. The parking brake doesn't require air to set. There are springs that hold the parking brake on. It will not release unless you have adequate air in the brake system.
