So I am installing new rotors and pads on a family members 13 Evoque. I got the front done and started the back. I tried putting P brake in maintenance mode but couldn't get it to work after 4 or 5 tries. So I just left ignition on with the P brake off. Shortly after pulling the caliper the car turned off automatically and then the P brake set pushing the piston out. Is their anyway to get the P brake to to release and put the piston back in? Or am I screwed and need to get a new caliper? Any help is appreciated.
