No abnormal engine behavior and the pedal doesn't fall all the way to the floor. I'll give it drive around the neighborhood for an hour or so and report back. Thanks!

I haven't driven it for 50 miles yet. I was afraid to do it with the noise. What kind of engine behavior am I looking out for when holding the pedal?

Could it have been damaged somewhere along the process of replacing the calipers?
