Default AIr in ABS pump or Master cylinder

I can't seem to figure out if I have any air in my master cylinder or ABS pump after my Brembo conversion for my 2011. There is a possibility that the master cylinder got emptied (not sure if it was complete, some fluid visible in bottom before I realized it was slowly draining over the few days I had the system open while I was doing other suspension work). Anyway, I vacuum and pressure bled the system 2 times. pedal feels ok, but maybe a little soft on the first pump. Took the car out and started to bed the brakes in. I can get the ABS to kick in when I need it. No ABS light on. Any thoughts?

how did you bleed the brakes? it could have air stuck up higher in the system. you might take it somewhere that can bleed the brakes with one of those big vacuum machines.

I bled with a vacuum pump at 20"Hg and also did the pump and hold and then the 1,2,3 method (1: pump, 2:hold and open bleeder, 3:close bleeder while holding pedal down). I just don't know what kind of feel I should have with the new brakes.

Just a heads up for the future. Place a stick between the seat and partially depress the brake pedal. This will prevent the fluid from leaking out of the MC when the system is open for maintenance.
