In this study, experimental methods were used to compare the consequences of employing snubbing versus dragging strategies to control the speeds of trucks on downgrades. Vehicle tests were performed on a long steep grade. A mobile dynamometer was used to study cooling rates and hot spotting. The basic findings of the study are: the average temperature per pound (kilogram) of brake drum is practically equivalent whether light dragging or snubbing is used; the hottest brakes will be cooler if snubbing is used; and on short downhill descents, the dragging strategy will cause hot spots to develop to a greater extent.
