2021 Honda HR-V EX Aegean Blue Metallic
Here is a video. Sorry about the squeak by my shoe it was wet. This was done on a level area in drive so the car wasn’t rolling. Note that if I press on the right side of the pedal it makes the noise. If I switch and press on the left side it doesn’t..^^ This post tells me that it's not a brake pedal issue. Could still be a brake system issue though.
Can you replicate the noise when the engine is off?
Does having the parking brake on or off make a difference?
Can you hear the noise better with all 4 windows down?
Although your 2021 HRV is under warranty, you could jack it up, spin each wheel while someone applies the brakes to see if you can narrow down the issue.
Have someone press the brake while you have your head under the hood listening for the noise.
Perhaps record a video of the noise and post it?
The video should show the brake pedal being activated corresponding with the noise.
Like was mentioned, Google "break" versus "brake".
