Dead easy two bolts, to remove caliper, pads are held onto bracket (not caliper), remove pads, insert new pads then you will need to push the piston back into the caliper & at the same time bleed of the surplus fluid from the caliper bled nipple (undo it). If you do not then by forcing the fluid back into the ABS unit you can flip the valve seals...
The new set of pads should come with four new bolts & a new warning sensor wire.
Be careful when removing & installing pads as the shims glued on the back are sided & directional, so you have two pads the same & two which are unique...the ones that are the same fit the outside face & the others are the inside face & look at which side is left & right. Also remember to fit the ABS sensor wire to the correct pad!
Calliper pin bolts 13mm socket & 17mm spanner to hold

Apply a small amount of Ceramic grease to the caliper bracket where the spring clips fit, this might be included with the pads, if not use this :-
