Hello,

One of the first item needs to be checked is the brake fluid.
If there is a leak in the system it will not build pressure on the brake system and the brakes will not function.
The brake fluid can leak out of any of the hoses or calipers.
Check the brake fluid if it is low/empty then that is exactly what happened.
This issue can also happen due to a faulty brake master cylinder, which is not creating pressure.

Here is a helpful article that covers all the basics:

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
