Hi all,
Just to let you all know, I've managed to bleed the clutch.
After repeatedly trying vacuum,back bleed with a large syringe with no joy i decided to use some air pressure from a compressor and hey presto job done in seconds.
I had read all the fixes on here but just couldn't get air out of system. Reading about the system many have struggled so if all else fails please try forcing air out with some pressure from a compressor. Obviously make sure you can control the pressure and that you have enough fluid in pipes so you don't just fill servo back up with air ?
Hope this helps someone else in the future ?
