Abstract
A compact, modular and versatile vehicle testing assembly for testing at least the brakes of an assembled vehicle comprises a pair of rollers adapted to support a tire of a tire and wheel assembly of a vehicle positioned on the testing assembly, with the pair of rollers being moveable relative to one another to alter the spacing there between. A drive system is connected to one of the rollers to operate as a drive roller for selectively imparting rotational motion to a tire of a vehicle tire and wheel assembly, with the other roller comprising a freewheeling roller to which rotational motion is imparted by a vehicle tire. A brake member is engageable with the freewheeling roller to selectively inhibit rotation of the freewheeling roller.
