Soft pedal after brake flush
I recently did a full brake fluid flush (ATE SL6) on my CL55 using my Motive pressure bleeder and now the pedal is softer than before. I think I may have gotten air in the system after sucking out the old fluid from the reservoir tank. I bled all brakes the first time using approx 15psi. I bled the whole system again using 25psi and only a few tiny bubbles came out but that's it. Pedal is just a bit firmer after second flush but still not right. I went through about 1.5 liters per flush.
So what do I do now?
A. Increase pressure to 30psi and flush again? (WIS says to use "greater than 2 bar" which is more than 29psi but many threads say don't use more than 20psi
).
B. Remove MC and bench bleed it?
C. Is there a switchover valve that needs to be actuated during the flush like in the older benzes which is preventing the air from coming out??
D. Flush with the 2 person method?
Thanks in advance for your help.

Just bleed a little at each corner.
