Nissan Sentra 2017 SV--Brakes Grinding only when AC is on

I own a 2017 Nissan Sentra SV with almost 90k miles. It was running
perfectly until I switched the AC on recently. Now, the brakes make the most
awful grinding sound. The sound goes away when the AC and Recirculation
Air button are OFF. This does not happen when I use the heat.

I will probably take it to the shop to be told that I need to replace all the usual
brake parts. However, I have a hard time believing the BRAKES are the
problem when the grinding only starts with the AC.

I have seen other posts about this problem on the internet, but I have yet to
find an answer other than taking it for service.

Thank you!
