This paper will describe GM technology for objective measurement of brake balance. Facilities will include the road transducer pad and torque wheel instrumentation. The need for multiple approaches to brake balance testing will be defined. Limitations of past methods, such as skid checks, will also be described. Statistical properties of data bases derived from these tests for relatively large numbers of production vehicles will be defined. This will assist other research activities in studying the primary safety performance for vehicles operating in North America.
