In hydraulic braking systems, the pressure applied at the brake pedal

is transmitted to the brake mechanism by a liquid. Since a liquid

cannot be compressed under ordinary pressures, force is transmitted

solidly just as if rods were used. Force exerted at any point upon a

confined liquid is distributed equally through the liquid in all

directions so that all brakes are applied equally.
