What is a primary disadvantage of multiple disk brakes?

The primary disadvantage of multiple disk brakes is that while they do provide substantial stopping power and great performance under certain conditions, they can struggle with heat dissipation compared to other braking systems. Due to the nature of how multiple disks are arranged and the friction involved in their operation, they can generate significant amounts of heat during use. In high-demand scenarios, such as prolonged braking or in situations where heat is not effectively dissipated, this can lead to brake fade, reducing their effectiveness and leading to potential safety concerns.

On the other hand, maintenance of multiple disk brakes is generally manageable, and while they may require more hydraulic fluid than single disk setups, this is not regarded as a primary disadvantage. Additionally, the durability of multiple disk brakes can vary based on materials and conditions, but they are not inherently known for wearing out faster than other types. This understanding highlights the importance of addressing heat management when utilizing this braking system to ensure safety and efficiency.
