I have Prius 2006, about 62000 miles. A week ago I was at my Toyota dealer for annual inspection. My car passed inspection, but service advisor wrote in my bill that my car needs front brake rotor and pads due to rust. The price he put $485.50 for this job. I'm not sure that my car needs all that because my brakes are good and I don't hear any noise. My questions are: 1. how to verify that my car needs a front brake rotor? 2. Isn't it too pricy for just front brakes? Are any advises?
