Answer :
Final answer:
If the antilock braking system (ABS) fails, brakes will function normally but without the anti-lock feature, hence wheels may lock up during hard braking.
Explanation:
If your antilock braking system (ABS) fails, it is true that the brakes will function normally. This means that, without ABS, your vehicle's brakes will still operate but without the anti-lock feature. However, during hard braking, especially under slippery conditions, the wheels may lock up since the system that prevents this is no longer functional.
It is important to note that ABS is a supplementary system that provides additional control during sudden stops; its failure does not mean a complete loss of braking capability but rather the loss of this enhanced feature. In practice, drivers should pump the brakes during hard stops if their ABS is not working, to mimic the effect of ABS and help prevent skidding.
As for the other options, the brakes will not become more responsive, will not automatically engage, and, while they could lock up during hard braking, this is not guaranteed as multiple factors such as driver response and road conditions also play a role.
