New Australian standards are in place for heavy-vehicle brakes

The new standard (AS 3450:2021 Earth-moving machinery – Wheeled or high-speed rubber-tracked machines – Performance requirements and test procedures for brake systems (ISO 3450:2011, MOD)) adopts ISO 3450:2011 with modifications for Australia, which specifies the minimum performance requirements and test procedures for the service, secondary and parking-brake systems of wheeled and high-speed rubber-tracked earth-moving machines, for the uniform assessment of those brake systems.
The new standard supersedes AS 2958.1-1995 and is an important step in moving away from the inadequacies of AS2958.
It focuses on performance measured in average deceleration, which makes it more consistent with other standards and methods. It also provides reasonable criteria that maps on to the standard outputs from an electronic brake meter.
AutoTest says its AutoStop Heavy complies completely with this requirement.

Brake testing with GPS
Many jurisdictions are changing their requirements for conducting dynamic brake tests to include the GPS location of where the test was conducted. This ensures the test was conducted in a suitable location and road surface/grade.
Most recently the Queensland government has adopted this requirement for all tests that are reported to the Department of Transport for mobile Approved Inspection Station (AIS) or personalised transport vehicles. All of AutoTest’s brake meters can be purchased with a GPS module or are able to be retrofitted with the module.

AutoStop Heavy brake tester
AutoTest explains that its AutoStop Heavy is an electronic in-vehicle brake-testing device that is fully compliant with transport-authority requirements across Australia, including AS2958 Australian Standard and ISO 3450 testing.
This Australian made brake meter is designed to test the service and emergency brakes of heavy and slow-moving vehicles, off-road transport and even forklifts.
Designed to be portable and user friendly, the AutoStop Heavy brake-performance tester measures average and maximum deceleration, stopping distance, test speed and pedal-force required to stop a heavy vehicle.
Once the vehicle has come to a stop, the brake tester evaluates the brake performance and prints the results of the test.
AutoStop Heavy comes with a data-logging facility that allows stored tests to be downloaded to a PC for storage and analysis.
By providing an accurate report and confirming braking performance, AutoTest says employers can protect personnel and ensure that vehicles comply with occupational health and safety concerns. Calibration is also internationally traceable through the National Association of Testing Authorities (NATA).
AutoTest explains that AutoStop Heavy is capable of providing physical evidence of brake performance before and after any vehicle alterations, mitigating risks. The device is designed to be easy to set up and records the test GPS location, providing the latitude and longitude of the test position.
