Have you tried having the caliper higher than the master cylinder til you get pressure?

I had a similar problem with the rear caliper on mine and I hadn,t quite nipped the banjo up far enough on the caliper :blush: So it might be worth a try?

If you can I have managed to sort something similar on the front brakes by topping the master cylinder up,tieing the lever back to the bars and leaving it over night with all the bleed nipples closed tight

.

Good to hear you,ve started to sort it dude.Good luck with the rest of the bleeding;)

Tim, best little tool I found to bleed brakes... Worth every penny.

The NAPA one worked very well but didn't last long. The bottom image Stockton Tool is from Cyclegear, more durable and works extremely well...

I've used this type for many years:
