In a two wheeler efficient braking becomes indispensable. CBS, ABS plays a significant achievement in meeting the required braking efficiency [2, 5, and 6]. Conversely for non CBS & non ABS motor cycles, braking efficiency [2, 5, and 6] becomes a challenging task for two wheeler OEM suppliers. This is because of the customers' affordability for the required degree of efficiency [2, 5, and 6]. This paper depicts the innovative design of brake drum [3, 4] pertaining to its functional aspect; catering to meet customer needs economically. Cast iron Brake drum [3, 4] is redesigned with an engineered solution which allows draining the water in rainy season. This has been verified though mathematical approach about contact [1] area between liner and brake drum [3, 4]. Thereafter proto part has been made as per 3D concept. Test Results of proposed design have been compared with the existing drum brake system.
