Right, Just bath bled it. Was perfect once I'd finished. Put it on the bike, set it up, wound the TPA in a bit until it felt right, then it went mushy and was coming back to the bar? The pistons haven't slipped in the mounts, and it's not showing any obvious signs of leaking. I wound the TPA out, pulled it, and the pads barely move. So it's leaking from somewhere, but I can't figure out where? - All hoses are done up, bleed bolts are tight, hose is fine. Lever piston looks fine.
