The working principle of hydraulic braking system is purely based upon pascal’s law, which states that the intensity of pressure exerted inside a closed system by the liquid is always equal in all the directions. The easiest way is to raise one side of the trailer and spin the wheels while someone applies the surge brakes at the coupler.
