Oh, I did it right - drove that car many thousands of miles on that brake job. I am quite able to do such things. It took me almost 2 days, though. If you watched me, about an hour in, you’d take away my tools.
I doubt it. More likely I'd help you learn better techniques. Or at least faster ones. A brake job (all four rotors and pads) shouldn't take more than a couple hours. Less, if you have fancy stuff like air tools and a lift.
YouTube videos can supplement your knowledge here, too.
