Yes this is indeed an easy task.
Jack up and remove wheel as per normal.
The brake caliper has two securing bolts to the top and the bottom, holding the caliper to the cradle. Remove the bottom bolt (requires a 13mm spanner for bolt and a 17mm spanner for the collar), this will allow the calliper to swing up and reveal the brake pads.
Replace the brake pads and reverse above
