ABSTRACT:
A method and apparatus is disclosed for dynamically testing the operation of a vehicle anti-skid brake system of the kind which has first and second sensors associated with first and second vehicle wheels and which operates, when the brakes are being applied by the vehicle to release brake force to both wheels when either sensor senses imminent lock-up of its respective wheel. The method includes the steps of engaging the peripheries of both wheels with the peripheries of first and second motor-driven rolls, driving the rolls up to a high peripheral speed, applying and maintaining the vehicle brakes releasing the motor-drive to the first roll so that the first wheel tends to lock-up thereby actuating the anti-skid system, reapplying the motor drive to the first roll, releasing the motor drive to the second roll so that the second wheel tends to lock-up thereby actuating the anti-skid system, and generating signals in response to the actuation of the anti-skid system by either sensor.
