I've just come to accept that I will need to work on the front brakes on an annual basis. I've lost count of the amount of brake jobs I've done on the fronts on my '99. Probably 7 or 8 now. I'll usually cut or replace the rotors and replace the pads if needed. Once I do this, I'm good for another 15-20K. I do the work myself and the cost of new parts is fairly low. I can live with it...

When you replace the rotors, wire brush all the rust off of the hub where the rotor mates to it. Also clean the mounting face of the rotor if you're putting the old one back on. You should also check the rotor for runout. Excessive runout can cause warping too. Runout should be no more than a few mils max.
