Agreed Arwyn.

What is the problem with some fluid loss, every time I change a caliper on either one of my cars or on a friends car, I always bleed that caliper and the other side caliper until I get new clean fluid out both sides.

I usually do the other axle as well. Does £10 or so in brake fluid and 40 minutes of the original posters time matter that much when you are getting rid of fluid that will have get some amount of water ingress in it.

That makes no ences to me
