Im at college training and actually did a peugeot you obviously remove wheel then the drum has a thin slightly domed disc which can be removed with flat end screwdriver and an soft impact hammer use socket set to remove bearing /nut then take the drum off by hitting it all around with soft impact hammer if stiff spray a lubricant like wd40 again use flat end chisel and gently hammer in groove between disc and back plate and prise drum from plate may take some time but will ease off eventually if you are changing linings do same to other wheel so when removed one set have other as a template to follow so that springs are replaced correctly hope this helps
