Agreed on 90k from one set.

I had a topaz that would do that. I never heard the wear indicator, just grinding when they were done. It's probably the remnants of a pad digging into a rotor. This problem is fairly evident when you pull the wheel off.

You can get the pads and rotors for between 80 and 120 bucks depending on where you go and what you get and it really is an easy job if you feel like tackling it.

Tools needed include: 1/2" or 13mm socket (can't remember which fits better), ratchet, breaker bar (or just a really long ratchet), C-clamp (to push the plungers back in), something to hold the calliper up with while you're working, brake cleaner, and the lug wrench and jack out of the trunk.
