What is brake lag?

Question

What is brake lag?

Answers

A. The time required for the brakes to work after the brake pedal is pressed

B. The distance between the brake pedal and the floor

C. The amount of air pressure used to stop the vehicle

Explanation

Because air takes time to flow through the air lines to the brakes, air brakes cannot begin working instantly. There is often a brake lag of at least one-half of a second between the moment the brake pedal is pressed and the moment the brakes begin to work.
