Do you know if that is the correct answer for sure?
I am not a science expert by any stretch of the imagination, and I am not up on my hydraulic skills, but I assume that's what makes it a hydraulic system and why it functions the way it does, because it's a closed system. I don't know what kind of outside pressure can be too much for it to override the system with greater force in some way that my mind doesn't understand.
But I know my toothpaste always splooges out unwanted after flights and I would think that's in a closed system to some degree, but outside pressure overrides that some how and most things I have traveled with in the past like that. I just wanted to be sure that there is nothing I have to be cautious about because I don't understand the science behind all that. I just know my toothpaste container splooges when first opened. Wanted to make sure nothing like that can happen to the brakes because I have never received pre-bled brakes in the mail before.
