SMT 2010, 47000 km.
First "deep clean" of the brakes ever last weekend. I don´t drive during winter time, and never on salty roads!
Drained the brake fluid through the air screws on the calipers.
Took the calipers out and pushed the pistons out using pressured air. Cleaned all parts with STP Brake Cleaner and a (used) tooth brush
The original Brembo pads had at least 3 mm thickness left, on all 8. I have new SBS pads in a box, and they have about 4,5 mm thickness. Didn´t see any reason to replace the original Brembo ones. They will live for another 10 000 km I believe.
All back together and it´s working as it should.
Only issue was the every time coming problem to air bleed the system... have patience!
Now it seems like it works as it should.
UPDATE 14 of July:
I have driven almost 2000 km the last week, including 2 track days, and the front brakes works good.
And also, the irritating noise when pushing the bike slowly forward (or backward) at the same time turning the steering, disappeared
