Zusammenfassung:	Actual performance is used to determine vehicle braking system maintenance requirements. Measures of wheel slip are determined (34) for each wheel of a vehicle during periods of deceleration. The determined measures of wheel slip are accumulated (36); and those accumulated for left wheels are compared (38) with those accumulated for right wheels of each axially associated set of wheels, those accumulated for one axially associated set of wheels are compared (42) with those accumulated for each of other axially associated sets of wheels, and those accumulated for tractor wheels are compared (46) with those accumulated for trailer wheels. A predetermined difference between measures of wheel slip indicates the existence of a possible problem with the brake associated with the wheel or at least one of the set of wheels for which the least wheel slip is determined.
