Brake squeak detected

Hello all, after 25k of trouble free experiences here we go with a little squeak when I depress the brake pedal, you can hear it in the background, any input or links to past posts greatly appreciated. I am taking it for the standard 5k oil service this afternoon and will ask them to look into it but want to be prepared if they come up with "you need new brakes, rotors and how about a new car" and the bill attached to it. This baby has another 50k trouble free miles to go, at least. Almost 150k in the odometer.

Thanks again!
