Which description of stab braking is accurate?
Correct answer: You release the brakes only after the wheels have locked up.
Answer options
- AYou keep steady pedal pressure so the wheels never lock.
- BYou release the brakes only after the wheels have locked up. Correct
- CIt is a technique that should never be used.
Why
With stab braking you push the brakes all the way down, let up as soon as the wheels lock, and press fully again once they start rolling; it is meant for vehicles without antilock brakes. Steady pressure that stops short of lockup is a different method called controlled braking.
