Doddle to do, the caliper is held to the caliper carrier by 2 bolts (item 44/45)some are hidden behind rubber bungs some are allen keys some are torx keys.
Remove the large spring clip (47)from the front of the caliper.
Locate and unplug the brake pad warning wires these just unplug and if you are careful pop out of the old pads and can be reused again.
Using a decent size flat screwdriver in from the top of the caliper in the slot, slowly prise the pads away from the disc, this will slowly push the brake caliper piston back into the caliper giving you enough room to fit the new pads.
Remove the 2 screws mentioned.
Lift off the caliper do not let it hang on the brake pipe.
Remove the pad left in the caliper carrier, one will come away with the caliper it has little spring clips that hold it there.
The two caliper retaining bolts screw into little sliders the just pull out and need a little grease on before refitting not copaslip!
Give everything a good clean and wire brush off then a little copaslip on the little ears on the brake pads and refit one to the caliper and one to the carrier then put it all back together.
There will probably be cables and other stuff in the way simply unclip and reclip back afterwards, sounds hard but is very easy.
So in anutshell remove 47 remove 59 remove 44/45 lift off 5 remove 56 done
