Check your rotors if you have a micrometer (somehow i end up with these things) and see if they are in spec. According to my manual- 21mm for front, 8mm in back (if you have disks). Pads should be obvious.
If your breaks are in spec, don't worry. I've yet to have to replace rotors on a car i've owned. I've replaced friends rotors in 3 years. If you have issues, glazed pads, pulsing, different story.
