Brakes Suddenly Stop Working

Brakes Suddenly Stop Working
Perhaps someone can help me. My daughter has a 1999 Nissan Maxima. Every once in a while the brake petal doesn't depress preventing her to stop. She fearfully called me not knowing what to do. After finally stopping and turning off the vehicle, I checked it and the brakes were working perfectly fine. My wife and I are afraid to have her drive it.
Could this his be a faulty brake booster or check value? I tested the booster by depressing brake petal with car off 10 times and held. Turned the car on and the brake petal depressed. This seems to indicate a working booster.
Any iseas what what could cause her brake petal to act this way so infrequently?
I look forward to your comments.
Thank you.

This is not the spot to be posting problems with your car. This Garage forum is for the structure we call a garage and the things that make it a garage, such as the lighting, the tools, the floor jacks, etc.
Since you have a 99, you need to post your car problems in the 4th Generation forum where many more people with the knowledge you are seeking frequent.
As for your problem, my guess would be either the booster or the master cylinder. Since the problem is not constant, it will require some expertise to find the cause.

How hard is the pedal when it does not depress? Is it rock solid hard, like not moving at all and no braking whatsoever? Or is it "pretty hard" but does actually brake if pressed hard? The former would be mechanical issue, and the later could be the vacuum issue.
