Brakes are generally considered a good thing to have on a car.
Just short of three hours of work—closer to two if you subtract the time spent before (changing clothes, laying out the tools and parts) and after (cleaning my tools and putting them away, tidying the workshop, washing, changing clothes).
I don’t have a micrometer, so I didn’t measure the pads and disks I replaced, but judging by eye, the outboard pads were fine, but the inboard pads were close to or at the legal limit, and the disks were well below it.
