@ 14:35 it shows him disassemble the EPB. He'd already used the scanner to set maintenance mode and retract piston, but if he hadn't, he would've used the T45 to walk the piston back into its seated position. he says that. On the assembly side, he used the scanner to rest the EPB. What isn't clear though, is how does the EPB get reset WITHOUT using the scanner as he did. I would imagine it's a process of turning it off & on a few times until it finds it's new position relative to the new rotors/pads. I'm pretty sure they all work this way.
