The complete seal kit from Honda - you will of course need one of these per side.

Piston dust seal.

Piston main seal.

 

Caliper sliding pin seals.

 

Banjo bolt washers.

 

---

And finally the three packets of grease, although very expensive at least the Honda seal kit is comprehensive. The correct grease must be used in the right area.

 

The red grease is for the piston dust cover.

The orange grease is for the lubricating the sliding pin.
 

And the clear grease is used for the edges of the pad, although it doesn't say anything on the bag, or in the service manual.
