Not sure how many slightly different types in MH over the years. But it's a "Hydro-boost", brake boost is run off power steering pump instead of engine vacuum and has electric back up assist pump.
I've had GMs version , in Astro van and diesel P/U with just PS to brake boost no back up pump.
Like anything on your coach good to familiarize yourself with how it functions . There are threads on them here like most threads, mostly when there's an issue ,so just don't panic reading, the system is pretty solid. Some extra attention to elect back up and PS belt, pump , fluid, or cooler ect is good idea as support of your braking power.
