Final answer:

The heat generated in a disc brake system during the braking process is dissipated primarily via the rotor, which radiates the thermal energy away, preventing brake system overheating.

Step-by-step explanation:

In a disc brake assembly, the heat created during braking action is dissipated primarily via the rotor. When the brake pads clamp down on the rotor, they create friction which transforms the kinetic energy of the moving vehicle into thermal energy (heat). The rotor, which is a large metal disc, then radiates this heat away into the atmosphere, effectively cooling the brake system and preventing overheating. It's essential for the rotors to be effective at dissipating heat to maintain the performance and safety of the braking system. Overheating brakes can lead to brake fade, which is a reduction in stopping power and a significant safety risk.
