Without hearing it, I can't be sure, but it could be: Pads not properly seated due to wear. I piece of a pad broken exposing a rivet. Worn down pads exposing rivets. Dust, dirt, pebbles in brake system. I had this problem before, it turned out the ball bearings in one of my wheels needed replacing. This might be the case if the noise is coming from a wheel.
The high pitched squeaking noise you are hearing is the warning device telling you your brake pads are worn out and need replacing. The grinding sound is the sound you hear when you ignore the squeaking noise and allow your brake pads to wear so much that the metal backing of the pad is rubbing against the rotor. Replace all brake pads on the same axle and have the rotors turned at a machine shop. You may end up having to replace the rotors if they are damaged too severely.
All fans will make a "whooshing noise" If there is a squeaking or grinding noise the fan motor needs to be replaced/refurbished.

You may very likely have bent the thin metal backing plate behind the brake rotor. That will cause the backing plate to rub against the rotor and make an awful grinding noise. Its not too hard to reform the backing plate away from the rotor.
