Bleeding brake problem

Just tried for the second time to bleed my brakes.

Followed all the instructions, got tonnes of bubbles out, was very patient, repeating the process several times and still no good.

The leaver pulls all the way to the bar with ease and have virtually no affect on the calliper.

Problem started when I undid the grub screw at the calliper and lost some fluid in the process a while back. I'm wondering if I need to put more fluid in as opposed to just bleeding the system?

Brakes are Formula RX and I'm using Dot 4 fluid as suggested by manufacturer.

I've serviced forks, swapped bottom brackets, true'd wheels and done pretty much every other job on a bike in the past but for some reason I can't bleed my bleeding brakes!

Brakes look quite healthy, as do hoses and they were perfect before I stupidly let some fluid out...

Any help would be greatly appreciated.

Thanks in advance, J.
I love the sound my tyres make on dusty single track!
