Hi and thanks for using 2CarPros.
Before anything, make sure the brake fluid isn't low.
Chances are one of the wheel speed sensors has failed or lost connection. You will need a live data scanner to determine what fault code is stored in the system and to determine if the wheel speed sensor which is indicated by the code is actually not sending a signal.
Here is a video that shows in general how a scanner is used:

I realize most people don't own a scanner. Often times you can rent one at a parts store or they will scan it for you. Get the code and let me know what it is. Next, a live scanner, which you most likely don't have, can monitor the wheel speed sensors while the vehicle is being driven. That is when you could check to confirm which sensor isn't sending a signal.
Let me know if this helps or if you have other questions.
Take care,
Joe
