The Australian Trucking Association (ATA) is reminding operators about the importance of a reliable brake system with the release of a new Technical Advisory Procedure (TAP).
The TAP details effective brake adjustment set-up, maintenance and compliance.
Why is this important?
The NHVR and RMS have agreed to extend the ongoing brake testing transition arrangements in NSW to January 31st, 2017.
As part of the brake testing transition arrangements, heavy vehicles that achieve a brake test result greater than 3kN/t but less that 4.5n/T, will be given an official warning on first time detection until then.
The new TAP on slack adjuster setup and compliance to the National Heavy Vehicle Regulator’s inspection manual is meant to remind operators about the importance of a reliable brake system setup and maintenance to ensure the safety of the fleet.
The advisory procedure detailed in the TAP was developed by the ATA’s Industry Technical Council, to emphasise the importance of the right setup in improving brake performance and ultimately improving safety.
Chris Loose, ATA senior engineering advisor explained,
“Understanding the correct adjustment for slack adjusters is important to improving brake performance and having safer trucks on our roads,” Loose says.
“We’ve seen longer stroke brake chambers become standard on a range of truck models over recent years, and it’s important that truck operators understand what version is fitted on their truck and how it should be set up and maintained.
“Getting the setup right will improve brake performance and improve safety.”
The post goes on to explain that the newly released TAP also includes advice on chamber stroke and re-adjustment lengths, identification of stroke on the brake chamber end cap, brake chamber stroke length, and correct mounting of chambers with slack adjusters.
More advice is also provided for operators in the form of information on a stroke checking tool. The TAP also details templates and guides for correct adjustment.
According to Loose, the TAP also gives some supplier links for service, maintenance and correct setup.
He also added that buying the right quality of equipment is crucial, as is keeping vehicles serviced and regularly maintained.
Mr Loose went on to state about the document,
“There is a range of suppliers of both manual and automatic slack adjusters, all with unique designs and methods of function,” he says.
“It is important to buy the right quality of equipment built to the appropriate SAE standards, and to ensure they are regularly serviced and maintained.”
