How do i remove the rotor after removing calipar

Remove centre cap bolts, remove then circlip in centre, remove that section, then look for 3 philips head screws in "holey" lock ring and remove screws(sometimes need to do with impact driver), remove lock ring after undoing screws, then undo silver ring (anti-clockwise) by putting philips screw driver in holes of silver ring with lines in it and turning, then remove disc and hub as assembly (hub does separate if you undo the 17mm bolts that hold the disc to the hub, must do up this ring firm then back off and then do up the old feel method way. align a line in silver ring with top notch of centre threaded shaft that ring goes on, to one of the sides then when you put "holey" ring back on you can get the lock screws into silver ring.
