Abstract: Vehicle brake testing apparatus of the type in which there are yieldable restrained pairs of tread plates engaging the front wheels and rear wheels of a vehicle in which there is means for producing an electrical signal depending in value upon the braking force on each wheel, means for producing a total braking force signal depending upon the sums of the signals, means for measuring the speed of the vehicle as it is driven onto the tread plates and producing an electrical speed signal, means for dividing the integrated total force signal by the speed signal to obtain a weight signal indicative of the weight of the vehicle and means for comparing the total force signal with the weight signal to obtain an indication of the ratio between the total braking force and the weight of the vehicle and indicating whether this ratio meets acceptable standards.
