There are a number of things that this could be, but the most likely cause is the brake light switch has failed or the fuse for the brakes lights has blown.
So, let's run through a way on how to test that.
First, I am attaching the wiring diagram below so you can check for voltage at the switch.
Here is a guide that will help with this:

If you have no voltage, then you most likely have an issue with the fuse so use this guide to test and replace the fuse:

You will find the layout of the fuses below as well. This is the 20A fuse for the tail lamps.
Please let us know what you find. Thanks
