ABSTRACT:
A method for dynamically testing the operation of a vehicle anti-skid brake system and for making a record thereof includes engaging a wheel of the vehicle with a rapidly rotating roller or the like and accurately measuring and recording changes in an appropriate operating characteristic of the wheel while the vehicle brakes are being fully applied with sufficient power to rapidly slow the roller to essentially zero rpm and simultaneously to cause the anti-skid system, if operating properly, to rapidly release and reapply brake force in a manner to cause the wheel speed to decrease in stepwise fashion. The rotating roller slips relative to the vehicle wheel during application of brake force so that the wheel will be accelerated by the roll during release of brake force.
