Brake pedal softness

There have been some comments about the F30's brakes feeling too soft, spongy, and lacking in feel.

My 335i Msport also has those negative attributes, and pretty much every other F30 I've driven has the same not so great brake feel.

Many descriptions make it sound like there may be air in the lines.
A few days ago I was testing out the brake pedal and noticed that when I come to a stop I can pump the pedal 3-4 times and the pedal feel FIRMS up.
This is odd as it indicates that maybe the brake booster is not providing proper pressure, especially for a firm feel with better modulation.

Try pumping your brake pedal while stopped and post what you feel.
Does the pedal firm up or stay the same?
