Did you check your drive belts. If they are loose they will slip and give off a high pitched sqeal.
When brakes get wet, the water can cause the brake pads to vibrate and create a high-pitched squealing noise. This happens because the water disrupts the friction between the brake pads and the rotor, leading to the squealing sound.

The squealing sound you hear when your car brakes are wearing out is referred to as a "squealer." This indicator is a strip of metal that when the brake pad wears down makes contact with the rotor making a metal on metal noise.
To reduce or eliminate the squealing noise from your disc brakes, you can try cleaning the brake pads and rotors, adjusting the brake calipers, or replacing the brake pads with high-quality ones. If the issue persists, it may be best to consult a professional mechanic for further assistance.
