i assume you mean the resivor, since you can't see inside the master cylinder.

even if it was all air, the master cylinder shouldn't allow anything back into the resivor with the pedal down. you have bad seals in the MC. the fact that your original one is bad is no shock, it's 11 years old. if the z32 part was used, the same is true for that one too. it's probably older and was beat on harder. if it was rebuilt, get a new one, those rebuilding companies are far from perfect.

get a new MC and bench bleed it first.
