Brake squealing is a common issue with bicycles, and several typical causes can lead to this problem:
Foreign objects on the brake pads or disc rotor surfaces: The brake pads or brake system may have become dirty. The recommended solution is to remove the disc rotor and clean it with alcohol. If the brake pads are contaminated with oil, they should be promptly replaced.
