The relative position of this valve wrt the other components in the
brake system is of no importance. They all "see" the same pressure.
"Pressure exerted on an enclosed liquid is transmitted equally to every
part of the liquid and to the walls of the container." (Pascal's
principle)
I suppose one could argue that LBC and "enclosed liquid" are mutually
exclusive concepts, but that's another topic.
