And that's why you are a dummie. Me? I'd change them as soon as the squealer starts squealing. We have to get our cars inspected here in West by God Virginia and if the inspector tells me I got around 10,000 left on the pad, I change them and use premium pads. Saves the cost of a rotor and I like to be able to stop. Besides... good pads make a big difference over the life of the pad and rotor... especially round these parts. You get what you pay for.
I guess it'd be different if you plan on getting rid of the car.
Depending on which car I use the most on a mail route, my front brake pads last from 4 weeks on my Buick to about 10 weeks on the Chevy. I use the cheapest pads I can get (the best ones I've ever used were the $9.99 ones from Auto Zone), takes me less than 30 minutes to change, and are much cheaper than a $30 rotor.
I NEVER turn a rotor unless it is warped, or I've gone "DUmmie" and let the metal backing plate on the pads get into the rotor. Some rotors are cheaper to replace than to turn.
Perky, my wife is from McDowell County, and she (as well as I) DEMANDS the best pads on our POV, and that's what she gets! It would be hard to explain how saving $20 on a set of pads didn't save a $15,000 truck from going over the side of a mountain. West Virginia is beautiful country, but it can and will BITE you if you're stupid. On a side note, the man where I get my car inspected knows me and how well I take care of a vehicle, and doesn't even bother checking the brakes or suspension. Lights, wipers, tires, all ok, sticker, gone.
