After a long drawn out process, the trucking industry can finally ask, is roller brake testing finally sorted? According to the National Heavy Vehicle Regulator, new roller brake testing procedures have commenced across Australia. This follows 18 months of testing and evaluation after it was found existing procedures were producing inconsistent results after national standards were brought in.
The national brake testing standard of 45 percent g, or 4.4kN/t, was released as part of the National Heavy Vehicle Inspection Manual in 2016,” says Les Bruzsa, NHVR Chief Engineer. “The NHVR has worked closely with Roads and Maritime Services and the heavy vehicle industry to look at why some roller brake testing methods deliver differing results, when compared to other in-service brake testing methods.
“The working group has now developed the National roller brake testing procedure with machines used by state jurisdictions to be updated over the next 12 months. The working group has focused on identifying issues and delivering a robust procedure that will be effective for all vehicle types using current roller brake testing infrastructure.
