A field survey was conducted to evaluate two procedures designed to measure the effectiveness of motor vehicle braking systems. Selected failure rates and agreement measures were computed using a recently developed unified approach to the analysis of multivariate categorical data. It was found that the procedures agree only weakly, and that the agreement varied with certain pass/fail criteria. On the basis of conditional arguments, a moving-stopping test was found to be more stringent than a wheel removal inspection.
