If its a P30 Chassis, like our 95 class A Chevy was, it has what is called Hydro Boost. The brake pressure is made by the power steering pump... (the way I remember) Ours also took a lot of pedal pressure, even though I had replaced parts and ours was in very good shape. It was Nothing like air brakes on a truck, or power brakes on your car... It was a learning experience for me.... Not saying it may need maint.... but,,, if in good shape, it still is different.... There is a yahoo group, look up MotorhomesP-30 It is a good group to learn about your chassis....
