To establish a uniform procedure for obtaining and determining a maximum temperature of brake fluid in the automotive braking system of vehicles equipped with disc brakes. This procedure is a uniform means of heating the brakes and the brake fluid and is not a simulation of any other test procedure. This code provides a test procedure for obtaining and determining extremely high brake fluid temperature encountered in the brake system of a vehicle that is equipped with disc brakes. Vehicles in normal operation may or may not produce brake fluid temperatures that are obtained in this procedure.
