THE EFFECT OF BRAKE DISC TEMPERATURE ON BRAKING PERFORMANCE

16768

In this experimental work, effect of increasing in brake disc temperature on braking performance was investigated. For this purpose, braking distance tests which the criteria of braking performance were carried out. The tests were conducted on a small-size commercial vehicle for different disc temperatures, pedal forces, the vehicle loads and for initial vehicle speeds. Test results of stopping (braking) distance were analyzed for the variation of disc temperatures. The results showed that the stopping distance is considerable increased when the disc temperature is increased for different vehicle speed and pedal forces. Typically, at the vehicle speed of 80 km/h and maximum pedal force for 63 °C disc temperature, 44.9 m stopping distance was measured. When the temperature is increased as 298 °C, stopping distance is increased as 52.71 m with the rate of 17.4% at road test.
