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.

What I mean is that your assumption is that reduction of brake line length from wits design, won't matter because fluid can't be compressed.

However, what I am getting at is that while the pressure of the fluid at contact won't be likely to change, the time at which it takes the pressure to contact at each caliper will change. The braking system is specifically designed so that each wheel when the brake pedal is applied,w ill brake simultaneously. If you remove the distance that the fluid needs to "travel" it applies before the other and we create a problem.

What I keep trying to point out here, is that the braking system here isn't completely fluid filled like you guys are envisioning, there is travel involved due to the design of the system, and because of that travel, reduction or addition of designed length, will change the braking dynamics of the vehicle.

Again, I want to reiterate the fact that I fully understand, agree, and comprehend what you are saying about a system where it is completely fluid filled full of a liquid that cannot be compressed, and how that makes length no longer matter.

I'm just here to tell you that the scenario you are juxtaposing, isn't applicable because that is not how the braking system is designed.
