How do you change brake discs on peugeot 407?

To change the brake discs on a Peugeot 407, start by lifting the vehicle and removing the wheel. Next, detach the caliper by unbolting it and carefully hanging it out of the way (do not let it dangle by the brake line). Remove the old brake disc, then install the new disc, ensuring it is seated correctly. Finally, reattach the caliper, replace the wheel, and lower the vehicle. Always ensure to check and adjust the brake fluid level as needed.
