I'm not sure what you mean by contained. Yes, the brake fluid is contained in the brake system consisting of the reservoir, master cylinder, brake lines and slave cylinders at the wheels.

I am not assuming the system is pressurized. It transitions from unpressurized before breaking to pressurized while you are breaking.

If the fluid were truly incompressible, the length of the line would not matter theoretically. Because brake fluid is slightly compressible, it has a very small effect that is not important in a practical sense.
