Final answer:
The main advantage of multiple disk brakes is increased braking power and improved heat dissipation.
Step-by-step explanation:
The main advantage of multiple disk brakes is increased braking power and improved heat dissipation. With multiple disk brakes, the braking force is distributed among several disks, allowing for more effective and efficient braking. Additionally, the multiple disks provide a larger surface area for heat dissipation, preventing the brakes from overheating during prolonged use.
