Question

which of these is an advantage of the disc brake system over drum brakes? select one: a. disc brakes transfer less heat to the atmosphere. b. disc brakes reduce the likelihood of brake fade. c. disc brakes do not need maintenance. d. disc brakes do not create annoying squeals and squeaks.

Explanation:

Disc brakes have better heat dissipation compared to drum brakes. This better heat - handling property reduces the likelihood of brake fade (a condition where brakes become less effective due to overheating).

• Option a: Disc brakes transfer more heat to the atmosphere (due to better ventilation) compared to drum brakes, so this option is incorrect.
• Option c: All brakes (including disc brakes) need maintenance, so this option is incorrect.
• Option d: Disc brakes can also create squeals and squeaks (though sometimes less frequently in some cases), but this is not a major advantage over drum brakes in terms of functionality.

Answer:

B. Disc brakes reduce the likelihood of brake fade.
