This document summarizes the design and analysis of a disc brake using finite element analysis. It begins with an introduction to brake classifications and an overview of disc brake components and operation. The author then describes modeling a disc brake in Pro-E and analyzing it using finite element analysis to study thermal effects and structural stresses under different operating conditions. Four materials were analyzed: nickel chrome steel, aluminum alloy, cast iron, and carbon reinforced polymer. The results showed carbon reinforced polymer had the best performance with stresses within limits and lower vibrations and weight. Therefore, the summary concludes carbon reinforced polymer is the best material for disc brakes.
