You could have air trapped in a loop or kink in the hydraulic hose in the headset. Get a large syringe fill it with brake fluid and connect it to the bleed point ar the disc and fill the system from the bottom. It clears the air every time.

How I bled mine ... I'm thinking by your description that you have hidden master maybe a grimeca one I removed cable from lever on master cyl then bled it by pumping lever on master cyl manually that way you get all the travel you don't get full travel when cable is connected and pumping with handle bar lever

As above to make sure you can get out all the air you can...

If still not firm... pull in lever and strap it to handlebar to keep it pulled in.. take lid off resevoir, and leave it overnight... lets the air slowly bleed out...

Worked for me in situations where I just couldnt bleed the b*stard....

Good luck

thanks for replies, ended up with wheel removed with disc on floor and scooter on bench and let gravity do its magic over night and bingo all sorted this morning.
