Brake caliper leaking

[Sizzle55]

So today I was changing my front brake pads and came across an issue. On the passenger side caliper piston (I think that's what is called) is leaking brake fluid. And the rubber gasket that goes around the piston is torn. So I ordered a new passenger caliper and will be changing first thing in the morning. Has anyone done this before? Any tips or advice anyone may have would be much appreciated.

Use new copper washers on each side of the banjo fitting. Used ones rarely seal up.
