During stab braking, when exactly should you release the brakes?
- A.Release after the vehicle has slid sideways for several seconds
- B.Release at a fixed count regardless of wheel behavior
- C.When the wheels lock up and you can feel or sense the skid starting, release just enough for the wheels to start rolling again
- D.Never release until the vehicle is fully stopped
Correct answer
C. When the wheels lock up and you can feel or sense the skid starting, release just enough for the wheels to start rolling again
Why
The release point is the lockup itself, because a rolling wheel has more grip and steering than a locked one. Waiting deep into a slide wastes distance and risks a jackknife before control returns.
