Brake system components were instrumented and installed in a fleet of full-sized cars operating in a metropolitan area. Pad and rotor temperatures were measured using embedded thermocouples. Triaxial accelerometers mounted on the caliper housings measured vibration and chatter during braking. Data was downloaded using a cell phone link. Additional information on the braking events was provided through driver survey responses. Data was analyzed to explain warranty claims.


Benefit:  Data collected from this commercial vehicle reflected actual driver usage patterns and operating conditions in this big city environment.
