Threshold braking is defined as what?

• A. Maximum pressure with wheel lock
• B. Light braking to avoid ABS
• C. Release brakes before ABS engages
• D. Maximum pressure without locking wheels or activating ABS

Answer: (D)

Threshold braking means applying the brakes with firm, maximum pressure to push the tires up to, but not beyond, their grip limit. The goal is to use as much braking force as possible while keeping the wheels from locking, so you maintain steering control and achieve the greatest deceleration. In practice you push the pedal hard enough to approach the edge of tire slip—the point just before lockup or ABS activation—so you get the shortest stopping distance without losing control. The other ways described don’t maximize grip or control: locking wheels destroys steering, light braking doesn’t use available friction, and releasing the brakes avoids the peak braking force.
