arrghh more annoyances with the car, another strange noise Options

[LewFX]

when im braking slightly uphill or on onramp that inclines, the car makes a weird grinding type noise just as its about to stop, feels like its from under the brake pedal area, and then follows with a loud squeel. before i take it in to someone to look at, does anyone have a clue what it might be? so krrrrrunkkkkk then squeeeeeel.
