The problem I've got is the link via the Honda site shows no retainer clips or springs, which becomes hard work to locate what should fit the caliper carrier ????I don't have the same model car as yours. If you click on the link supplied earlier, enter your reg into the Honda parts site and select continue when your model comes up, scroll down the diagrams until you come to the brakes. It will give you the part numbers. You can order from them or try to source cheaper alternatives on ebay for example.
Eurocarparts have springs and retainers for my model.
I know, this is the first caliper I've come across to not have shims or clips, I have looked on the link you've given me and this link does suggest there are clips that can be fitted.Yes your brakes are different to mine and do not have the clips or springs on the rear but do have a shim set, item 13:
Does have a spring/clip on the fronts, item7:
Maybe the retainers are attached to the pads.
