Power steering and brake fluid rarely gets any love in most cars. The systems are robust enough that they often last a good long time anyhow. My point was simply that there's no telling how long they'd last if the fluid were changed periodically. Over longer periods of time the rubber hoses deteriorate on the inside and contamination causes problems - so eventually changing them out helps preserve the pump/rack too.

Or one can drive it til it breaks and then fix it. It's another version of the Fram oil filter commercial - pay a little now or pay more later.
