Having the knowledge of the basics of how the system works is not an unreasonable expectation.
This is the purpose of my question, to learn more. In general, people have posted a lot of helpful information here in both respectful and dis-respectful tones. The end result is, hopefully, people are learning about air brake systems.
I don't even own a coach yet, so I have time to learn!
Thanks everyone. This has been educational. And remember, newbies may ask dumb question, but if you want them to learn instead of tuning out, just be nice...
