Abstract
Brake testing of large mining trucks was commenced in British Columbia in 1969 following an accident involving the failure of the service brakes of a diesel-electric rear dump truck. Since then, over 10,000 tests have been performed by mine operators and vehicle manufacturers on haul trucks with load capacities ranging from 35 to 350 tons. All tests have been carried out on fully loaded vehicles operating on downhill grades from 8 to 11 per cent. The development of the program is reviewed and improvements in brake performance achieved during the past decade documented. Selected brake test results are presented to show comparisons between earlier test results and those now being achieved. Problems encountered in maintaining acceptable braking performance are examined and future trends and developments from a regulatory authority perspective are considered.
