Hi Akimbeau,
I had a similar problem when I upgraded to the wilwood dynalite front brake kit. I also replaced my master cylinder. I was surprised that my brake pedal was soft and I did the same as you I bled them again but to no avail. The problem was that I had an older style proportion valve and with the larger upgraded rotor my proportioning valve was insufficient. I had to replace the proportioning valve with a wilwood adjustable proportioning valve. Summit Racing (Wilwood Brake Proportioning Valves 260-11179). This cured my soft brake pedal.
