are you sure it is coming from right front wheel? I mean has anyone been outside the vehicle when your braking or does it just sound like that to you inside the vehicle? I ask because last summer same thing happened to me, and I was SURE it was coming from right front wheel, and it was a rear rotor, replaced both rear rotors and brakes and was fine, also I would use e brake instead of brake pedal to avoid the horrible noise and it did not make the noise with e brake.
