Understanding the Brake Triangle: An Integrated Approach to Vehicle Braking Safety Braking performance is widely acknowledged as one of the most critical safety functions in any vehicle. Yet discussions about braking tend to focus almost exclusively on the friction components—pads, discs and drums—while overlooking the interconnected systems that govern how braking force is generated, transmitted […]
Take the uncertainty out of shock absorber diagnostics Suspension performance plays a direct role in vehicle stability, stopping distance, and overall handling. As part of the braking triangle, the condition of each shock directly influences how consistently the vehicle maintains road contact during braking. When damping performance deteriorates, wheels can momentarily lift or skip across […]
Modern vehicles rely on precise engine management systems to deliver performance, efficiency, and low emissions. Central to achieving this is the careful monitoring and control of combustion. The AutoGas Four or Five Gas Analyser provides automotive professionals with a powerful, portable solution to accurately assess engine health, tune performance, and verify emissions compliance across diesel […]
Shock Pro provides real-time, high-accuracy suspension testing so workshops can act before problems escalate. Suspension wear is often gradual and difficult to spot with visual checks until it starts affecting ride quality, handling, or tyre wear. For workshops and technicians, identifying worn or degraded shocks and struts early is essential. Even minor wear can compromise […]

AutoStop brake meters measure deceleration (braking efficiency) directly (which is the design parameter used in original homologation) to an accuracy of 2%. Distance is calculated by the meter in its internal computer using the average deceleration measurement, time to stop (from the internal real time clock – accuracy 1.0%) and the assumption that the final speed is zero. The double integration process involved in the mathematics compounds these measurement accuracies and dependent on the shape of the deceleration versus time trace can generate a different result. The difference will be much less than that obtained from using any peak deceleration instrument such as a Tapley meter. The difference is due solely to the mathematics and is not a function of the AutoStop meter. Regulators in certain jurisdictions still use “distance to stop” – because in the 70’s and 80’s direct measurement of braking efficiency to an accuracy of 2%. The regulations will “catch-up” eventually.

When should I calibrate my Workshop Pro?
Calibration is required yearly. This can be done yourself through BrakePro app by going to SETTINGS
*IN NSW YOU MUST SEND YOUR WORKSHOP PRO AND PEDAL EFFORT SENSOR TO US FOR YEARLY CALIBRATION.
When do I need to send in my Workshop Pro?
You do not need to*. If you are having issues with the Workshop Pro (i.e. Won’t charge or won’t turn on), you can take the device to your nearest Distributor. Alternatively, call our service line ( 3 8840 3016 ) for advice before sending your unit back.
My unit prompts me to update the BrakePro app but shows an error when it tries to install.
Contact Service Team and they’ll walk you through this issue.
Figure 2: Workshop Pro in position ready for testing. If the unit is moving in the seat, place on the floor of the passenger seat. Supplied velcro will secure in place.
When activating my unit, I get an error such as ‘Address field too long’ or similar.
Please check your address. If the address is very long you may need to abbreviate it. Do not use special characters such as commas or slashes, as these will trigger errors. Just leave a space in their place when possible.
The app is running slowly when sorting out stored tests.
Please clean up tests regularly by transferring them to the computer using the USB cable.
The time on my unit is wrong, how do I fix this?
Change the time to AUTOMATIC if you had changed it manually. If it’s on network time but still incorrect, connect to a network to get the updated time. The time zone may be wrong, so swipe up on the bottom of the screen and press the circle button. Once you’re on the home screen swipe on the middle of the screen to open up the list of apps.
