Undo the calipers, lift them so the nipples are at the highest point, and re-bleed, and i think you will find it works
Re-bleed the whole system aswell
cheers for comment but i have already done this.
i have taken rear calipers off and bled them and got every last bit of air out.
still travels to the floor
