I had a similar problem with a Husqvarna 125. The brake simply would not get a hard feel despite lots of bleeding. It turns out the problem was one of the little springy anti-chatter/squeal clips that the pads rest on had gotten cock-eyed and was jammed between one piston and the caliper. It wasn't letting one of the pistons put any squeeze on the pad, so it took a lot more lever travel for the other piston to flex the pad into the rotor and give any braking power. I ended up just pitching the clip, and now the brake works great. Of course, you've been in your caliper half a dozen times, now, so you probably don't actually have this problem.
