Welcome to the forum! This is the ABS modulator and pump assy. Was anything done before this happened? Any warning lights on the dashboard? Any work done on the brake system?

Brakes are working ok. During my commute, car bahaves properly and no issues besides the random noise are found.

It randomly occurs during driving. We figured that revving the engine was the only way to reproduce the issue.

Any other issues? Lights flickering?

No sir. Car behaves normally except for this random noice which has been occurring more often in the past year.

Check for voltage at the battery when revving the engine. See what's the highest voltage you are getting. You might have an Overvoltage situation.

From the behaviour of the ABS pump it sounds it is normal procedure that it makes more pressure , but the sound it makes it looks like something is binding inside the pump.
