Thanks c1800. I can't find any images, but I found this on the skandix site which shows my setup.
The brown lines are hard lines and you can see on each front caliper two hard lines which then attach to two flexi lines, which then run to hard lines on the inner wing.
The fittings on the end of the calliper hard lines and the fittings on the inner wing hard lines are all the same.
Hope that makes sense. I'll try get a photo of this on the car when I'm next there.
As for back flushing the block, I'll give that a go also. That's an incredible amount of debris that came out of yours!
