You could also rotate your tires at the same time while doing the check, if you are so inclined.

If you jack the car one wheel at a time you should pull the handbrake, the rears will be hard to spin then

I had my car lifted in N and no park brake on. Rear hubs could be spun with a finger. Front hubs were hard to rotate without the wheel for extra leverage, just because of the drive shaft and stuff.
We opened up the brake calipers to add brake pad return springs (from the OEM single one on the leading edge of the pad to a pair) but even with the pads visibly detached the front hubs were hard to spin.

If you use this method to test brake drag then you have to compare left front to right front and left rear to right rear, not front to rear.

I found my brake pads would stick occasionally. You'd need to test frequently.
The heat check is quick and requires no instrumentation, just some gymnastic skills if you have full wheel covers as you have to get behind the wheel then.

If a brake is hot you can feel it in the top of the wheel well too.
Waving above your tires is the ultimate quick check.
