Operation & SafetyQuestion 46 of 60
The total stopping distance for an air brake vehicle includes which of the following?
a.Only braking distance
b.Only perception distance
c.Perception and reaction distance only
d.Perception distance, reaction distance, brake lag distance, and braking distance
Explanation
For air brakes, total stopping distance is made up of perception distance, reaction distance, brake lag distance, and braking distance. Air brakes have an added brake lag because it takes time for the air to travel through the lines and apply the brakes. This makes the total stopping distance longer than for hydraulic brakes.
