Variations in performance and torque output of cam operated drum brakes are considered using finite element techniques to take account of brake shoe flexure and lining pressure distribution. Both equal work and floating cam modes of operation are discussed and predicted results are compared with those obtained from dynamometer tests. Changes in pressure distribution which arise from thermal expansion and wear are shown to affect bedded brake performance, while unbedded brake performance is affected by incomplete contact between lining and drum, coupled with the proportioning of work between the leading and trailing shoes of the brake.
