These 10 animal facts will amaze you. The Prony brake is a simple type of dynamometer used to measure the amount of torque produced by a motor or engine in order to determine its brake horsepower rating. The device was invented in 1821 by a French engineer named Gaspard de Prony, and continues to be widely used by tractor and heavy equipment manufacturers.
Most proportional brake controllers measure the tow vehicleâs rate of deceleration by means of a pendulum. The quicker you slow, the further the pendulum is displaced, via inertia, from its at-rest position. This creates an electric signal to your trailerâs brakes that is proportional to your deceleration rate.lectric-brake systems have been employed for several decades on most trailers that have any significant weight. Each trailer with electric brakes, in turn, also requires that the tow vehicle be fitted with a brake controller.
