    I used the ebay kit. I managed it, but it was a bit tricky.

    Make sure you have the tool to push the piston in. I found trying to get the rubber boot to seat properly was the most challenging. Fit the new main seal, get the boot fitted in the caliper, loosen the bleed screw and put plenty of the assembly grease on the main seal and on the inside of the boot, then push the piston in.
