Question 1 of 20

'Brake fade' is a loss of effectiveness of the brakes when they overheat. When would 'brake fade' be most likely to happen?

On a long journey

On a long downhill gradient

On the approach to hazards

Because the vehicle will suddenly roll backwards

Because it will cause the air pressure to rise

Because the service brake may not stop you

Because it will make the warning light go out
