Changing rear brakepads on a 2015 peugeot 308 SW, and making a piston reset tool

In this video I replace the rear brakepads on the Peugeot 308 SWII from 2015. I needed an tool to push the piston back, so I welded one.

It is an manual brake

Do you have electric handbrake if so how did you get around this as it has to be off. Thank you
