The technician takes off the caliper bracket first, followed by the caliper hose. From there, they'll get the new caliper in, connect information technology back to the caliper hose, and put it all in place. And so, they'll crack the bleeder valve on the caliper and use a pump to go rid of whatsoever 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 meet if at that place's pressure. Equally a final touch, the technician volition reopen the bleeder valve, hook up their pump, make certain there's no air in information technology, and close it dorsum upward.
