Which brake type supports heat dissipation through a rotating friction surface exposed to air and can incorporate internal ventilation?

Correct answer

Disc brake.

A disc brake. Pads act on the disc; ventilated designs support heat removal. This does not guarantee freedom from overheating: excessive thermal load, misuse or faults can impair braking. A drum brake is a different construction.
