Abstract
This paper is a result of the advent of new and much more stringent braking codes that are evolving for the braking performance of off-highway open pit mining trucks. The paper reports a series of actual truck performance tests to learn if stopping performance is predictable, to learn about the fade characteristics of the available linings, and to compare the actual brake performance to the theoretical performance. Various combinations of load, grades, and speeds were used for comparison.
Results show that designing a brake system to its static K value is not acceptable, that a level equivalency test of stops on ten percent grade is not practical, and that to insure similar linings will behave similarly they must be tested.
