If they only squeak when braking don't worry about it. The noise will eventually go away (assuming you did not use anti-squeak). If you did use it and there making that noise, you may want to double check the install. If the pads didn't come with anti-squeel, and you absolutely can't stand the noise. Take a trip to your local auto store, it should be cheap. I used CNC "disc brake quiet" and havent had any issues.
