Now take this one step further and measure the drag. Jack up a wheel, wrap a string around the tire, and pull with a spring scale. Then push back the brake pads and repeat. The difference is a direct measure of brake pad drag for that wheel.
Repeat for the other three wheels. Then report the total drag here, and we can estimate the effect on gas mileage.
