Hi GerardMartin,
Clearly if you have a pedal going to the floor then you have air in the system or a leak where fluid is escaping.
If all of this in the guide below checks out then I would suggest trying to break the system down in components so you can test each one. Basically, get some old metal brake lines about 4 inches long and fittings for each line coming off the master cylinder. If you plug the ends of each of these lines so that you are just testing the master cylinder chambers and if it has a hard pedal then you know it is not the master cylinder. Then just remove and connect one line actual brake line at a time and bleed the system again. This way, you will find which leg of the system is the issue.
This is a little unconventional and may take a little time to set up but it is very definitive in finding where the issue is. Let me know if you have questions.
