Summary:

Hayes Lemmerz has patented a straight 42 fin rotor design which has air entry from the inboard and outboard side of the brake rotor. In a previous brake colloquium, we reported that a 5% increase airflow occurs in this design compared to the conventional 100% inboard entry rotor. We have now studied the thermal cooling rate and distortion due to temperature on the dynamometer. The current Hayes Airflow Rotor Design has exhibited 100 degrees F lower peak temperature and 50% less coning when compared to current production rotor design. More work is being done to analytically understand the airflow and thermal distortion of the rotor compared to instrumented vehicle tests like DST (Detroit Suburban Traffic), and LACT (Los Angeles City Traffic)
