Brake Temperature Tests

A road test has been conducted on a 2008 Ford Windstar van mounted with a SCA rotor on the
passenger side and a cast iron rotor on the driver side. The van was driven downhill with a series of hard
braking to increase the brake temperatures (FIG 6). The temperatures of the SCA rotor, the aluminum
wheel against the SCA rotor, the cast iron rotor, and the aluminum wheel against the cast iron rotor were
measured immediately (FIG 7-9) at the end of downhill braking. FIG 10 presents the downhill braking test
result. The yellow curve is the temperature of the aluminum wheel against the cast iron rotor and the light
blue curve is the temperature of the aluminum wheel against the SCA rotor. The purple curve is the SCA
rotor rubbing surface temperature and the dark blue one is the cast iron rotor rubbing surface
temperature. The road test results further verify that the SCA rotor temperature is much lower than that of
cast iron rotor due to the heat transferred to the adjacent aluminum wheel more effectively. The
dynamometer comparison tests demonstrated the same phenomenon.
