The technician takes off the caliper bracket first, followed by the caliper hose. From there, they'll get the new caliper in, connect it back to the caliper hose, and put it all in place. Then, they'll crack the bleeder valve on the caliper and use a pump to get rid of any trapped air leftover from manufacturing or sitting on the shelf. They'll close the reservoir and make sure that the reservoir is topped off before going inside the car and pumping the brakes a few times to see if there's pressure. As a final touch, the technician will reopen the bleeder valve, hook up their pump, make sure there's no air in it, and close it back up.
