New pads and rotors -- "whirling" sound when braking?

I had new OE rear pads and rotors installed on my 2016 F83. Indy shop did an outstanding job and cleaned everything thoroughly including the calipers. Anyway the car now makes this weird “whirling” sound when depressing the brake pedal. It’s not a squeal or anything like that. And the stopping power is great. (I replaced the lines with stainless steel lines from ECS.)

I have read that this sound is normal with new pads and rotors and goes away after a while, but I want to ask you fine folks. Thanks.
