As powertrain performance of vehicle improves, brake load is gradually increasing. But it is not easy to increase brake size due to increment of cost and weight despite judder and fade problems are worried in field. Cooling-duct which provides additional forced convection to cool front brake is being considered instead of increasing brake size. However, cooling-duct causes loss of aerodynamic that increases drag coefficient of vehicle. This paper covers the optimization of brake cooling system including cooling-duct, deflector on suspension parts to direct air into front brake and dust cover so that minimize aerodynamic loss and maximize brake cooling performance. The optimal solution had been derived from thermal and aerodynamic simulation with CFD and verified through experimental test with vehicle. These results are expected to provide useful guidelines for designing brake cooling system efficiently in early development stage so that robust against judder and fade problem without increasing brake size.
