Padding my bill?

I recently brought my car in to the dealer for my 30,000 mile check up. I admit i was a few miles over the 30,000. But when I was told that I needed a brake flush and a power steering flush. I declined.

I know nothing about cars, unfortunately. But I am the only owner of a 2006 Ford Focus. I have had no accidents with my car. I have been consistent with my so many mile inspections granted some have been done a little late. To me it seems as if they are trying to pad my bill. How can I with only about 32,000 miles need these to flushes that they want 188 bucks for.

Please help.
