Blue arrow is pin that holds pads in, it may have splitpin in the end. take out bolts that hold caliper inplace, remove plastic cover, get a bar/pole and slide in betwen pads and prize open (all the way) remove pin and slide pads out, slide new pads in, replace pin, fit caliper back on to bike You may need to use a small clamp to push pistons back if bar/pole is not getting them fully back, but care is needed so leave old pads in till prize pistons open if you can http://www.tbray.org/ongoing/When/200x/2003/05/07/c-clamp.png always easier to undo the reservoir lid first b4 you push the pistons in as it helps relieve the pressure in the system but be carefull the fluid don't overflow as it will dammage the paint! if it does overflow clean it straigth away! Just my 2 pence worth!
