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.
Reapply pressure until you feel one of the wheels start to lock up, ease off slightly and continue this movement, tracking the threshold until you stop. As the vehicle slows, you can brake harder before lock-up will occur. The more slippery the surface, the less you will be able to push the brake before a wheel locks. The skill in threshold braking comes from being able to linger just short of lock-up. To threshold brake well requires much effort and concentration.
