Common advantages of brake discs include excellent braking performance, good heat dissipation, ease of inspection and replacement, and stability during emergency braking. However, there are some drawbacks, such as the potential for noise, the need for frequent maintenance, and the possibility of limited braking performance in wet conditions. In addition, different types of brake discs have their own specific advantages and disadvantages. For example, although carbon ceramic brake discs have excellent performance, they are costly and difficult for ordinary vehicles to afford.
