Application
This unit describes the performance outcomes required to inspect, service and repair auxiliary braking systems. It involves preparing for the task, inspecting the system, servicing and carrying out any necessary repairs to the system, performing post-service or repair testing, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The auxiliary braking systems include those of agricultural machinery, heavy commercial vehicles or mobile plant machinery. The unit applies to vehicles or machinery fitted with speed reducing or control devices, such as engine brakes, exhaust brakes or hydraulic or electrical retarders.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Evidence of Performance
Before competency can be determined, individuals must demonstrate they can perform the following according to the standards defined in this unit’s elements, performance criteria, range of conditions and foundation skills:
inspect, service and repair the auxiliary braking systems of two different vehicles or machinery.
Evidence of Knowledge
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS)
identification, function and operating principles of auxiliary braking systems and their components, including:
internal engine compression braking
external exhaust braking
hydraulic retarder
electrical retarder
control circuits
inspection procedures for auxiliary braking systems
service, repair and adjustment procedures for auxiliary braking systems
post-repair testing procedures for auxiliary braking systems.
Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the auxiliary braking systems that they have serviced and repaired, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
manufacturer auxiliary braking system specifications
two different vehicles or machinery with auxiliary braking systems requiring service and repair
tools and equipment appropriate for inspecting, servicing, repairing and adjusting auxiliary braking systems.
Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.
Skills | Description |
Learning skills to: | locate appropriate sources of auxiliary braking information efficiently. |
Reading skills to: | interpret information from manufacturer and workshop literature when seeking auxiliary braking system specifications and procedures. |
Writing skills to: | legibly and accurately fill out workplace documentation when reporting inspection findings, making repair recommendations, and recording parts and material used. |
Numeracy skills to: | measure auxiliary braking system components and use basic mathematical operations, including addition and subtraction, to calculate distances, tolerances and deviations from manufacturer specifications. |
