CARS.COM — If you ’ ra golden, the screaky or squeaking noise that your brakes make when you first drive your car in the morning, particularly after rain or snow, is just surface rust being scraped off the rotors by the brake pads the first few times you apply the brake bicycle.

Another possibility is that the brake pads are loosely mounted, or the shims that hold them in position have corroded or become free.
