Question 61 of 120

Why is brake fade a particular concern for a heavily loaded tank vehicle on a long descent?

Pick an answer

Brake fade only affects the parking brake, never the service brakes
The extra weight demands more braking force, and overusing the brakes on a long grade can overheat them until they lose effectiveness
Brake fade is an outdated myth left over from older trucks and does not occur at all in modern air brake systems, thanks to improvements made decades ago
Heavier vehicles are actually less likely to experience brake fade than lighter ones

Correct!

Not quite. The correct answer is highlighted.

Show answer

Correct answer to question 61 (Tank Vehicles): The extra weight demands more braking force, and overusing the brakes on a long grade can overheat them until they lose effectiveness

Why

More weight means the brakes have to work harder to hold speed on a long descent, and brakes worked too hard for too long build up heat until they fade and lose stopping power.
