Its not that odd that you need a pad change after 3+ years. Its simple to do it yourself... OEM style pads will work fine for you.
If you have rear drums, then its a tad more difficult...but still able to be done in your driveway. Just go to Autozone/Advance/Napa ect and get the $20-30 pads they offer.
Oh and gsd Dan...I'd say Wow, you still have the original pads? 8.5 years old? Prob couldn't hurt to swap them out.
