AThe brakes are applying uneven pressure across the axles

DFront-to-back liquid surge is shifting weight toward the front of the vehicle

✓ Correct answer: D. Front-to-back liquid surge is shifting weight toward the front of the vehicle When decelerating, unbaffled or partially filled liquid surges forward, adding momentum to the front of the vehicle and making it harder to stop — a phenomenon the CDL manual calls front-to-back surge.
