Here's another thought. You mention having the calipers "serviced". If the seals were replaced, they take time to bed in. Even with a coating of brake fluid or sil-glide on rebuild the pedal will often feel soft on initial push.

This is caused by the square section piston seal slightly grabbing and pulling back on the Pistons. Very similar to Knock Back of the pads on a track car.

No amount of bleeding will fix it. Just have to put a few hundred miles on the car and get new seals broken in.

Just another thought.
