    Impossible to dtermine with out looking.

    Are the rotors clean and straight?

    Are the rotors hitting the pads?

    The sources of squeal are:

    -dirty pads or rotor
    -misaligned caliper
    -misaligned mounting hardware (frame or fork tabs)
    -damged components

    Most likely it's the pad to rotor alignment, which should be parallel and perpendicular and centered, if 2- or 4- piston system.

    The next most likely problem is contamination, so use Isopropyl Alcohol to clean the rotor and pads....

    Any more details you can give?
