Question:

Which of the following will be true about your brake function if your anti-lock braking system (ABS) fails?

Answer: You will still have normal brake function and will just need to get the ABS repaired soon.

Explanation
Losing the ABS function does not change the basic parts of your truck, so you will still have the same brakes that you have always had. Simply use them and get the ABS repaired as soon as possible. There is no need to panic, unless your system shows other and more serious warnings.
