How do you replace rear disks on peugeot 307?

To replace the rear discs on a Peugeot 307, start by lifting the car and removing the rear wheels. Next, detach the brake caliper by unbolting it and hanging it securely to avoid straining the brake line. Remove the old brake disc by unscrewing any retaining screws and sliding it off the hub. Install the new disc, reattach the caliper, and ensure everything is tightened properly before replacing the wheel and lowering the car.
