...and back on, since you would normally first loosen the parking break pads (via the star wheel) and then retighten them once the rotor was in place. Lots of edited-out steps that someone doing this job for the first time would have really needed to see.
First off u never once showed anyone how to remove the rotors themselves. A lot of work just to get those off. That's the hardest part typically. Like loosen the emergency brake to pop off rotor or hitting with hammer while prying it off from side.
