초록

The purpose of this research is to reduce the weight of the brake system of vehicles and to increase braking performance and its durability and to shorten the stopping distance. The plans for light-weight vehicles are to develop light weight material itself which possesses superior properties and another way is to improve the manufacturing method of materials which have the better mechanical properties. And the materials used for this are aluminum alloy, magnesium alloy, titan alloy, steel, other metals, plastic, ceramic materials etc. In thisresearch, aluminum is used for the main body of the break to reduce the weight of the brake and cast iron(SCM4), stainless steel(SUS304) and titan alloy(Ti Gr2) are used for the outer ring shape plate and assembled with bolts. Dynamometer test are braking performed on the brake disc. Based on the test results, stainless steel(SUS304) is optimized for the light-weight brake disc.
