If you got all the fluid out then yes.

i would say it would be fine, as long as you got 99% of it out. To be sure, Since you did not hit the break pedal, I would bench bleed the master cylinder.

Key: did not push brake pedal. Those guys are right.... as long as you got most, and, and I define 99% as most - out you will be fine. There is no harm in bench-testing master cylinder as Rowefast said. Just a lot of time -consuming work....but brakes are a life-and-death system, and you will have to bleed all four corners of wheels. But that is your call Aleta. I carry my grandkids in my car and if there is even the very slightest chance of a brake problem ....personally, I would spare NO expense in making sure brakes are tip-top

I would bleed the system. You could also flush it with some brake line specific cleaner.
