No brakes

I just made a panic stop and the pedal went to floor now I have very little resistance when I push brake pedal with or without vacuum booster.
No leakage and the reservoir is full. Is it the master cylinder?
Thanks.

The Diaphragm is properly located.

The seals in your master cylinder are bad.

Thanks to all

I replaced the master cylinder and now have brakes.
I appreciate the comments from all of you.
Also the post regarding the brake indicator light staying on was helpful, just a matter of pulling the switch and moving the piston back a little so the switch plunger was in the correct position.
SEMPER Fi, Mike
