Application
This unit describes the performance outcomes required to remove and refit wheel hubs and associated brake components during the rectification of faults in steering and suspension systems. It involves identifying and confirming work requirements, preparing for the work, removing and refitting the wheel hubs and associated brake components, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The hubs and associated brake components include those of light vehicles, four wheel drive vehicles or light commercial vehicles. This unit does not involve servicing or repairing braking systems.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

park braking devices
wheel bearing types
basic operation of braking systems, including:
hydraulic braking systems
mechanical braking systems
types and applications of brake hydraulic fluids and wheel bearing greases
procedures for removing, inspecting, refitting and adjusting wheel hubs and associated brake components, including:
brake bleeding
brake and park brake adjustment
wheel bearing lubrication and adjustment
post-fitting procedures and checks of wheel hubs and associated brake components.
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 vehicle wheel hubs and brake components that they have worked on, 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 wheel hubs and associated brake component specifications
two different vehicles for removing and refitting the wheel hubs and associated brake components specified in the performance evidence
tools, equipment and materials appropriate for removing, inspecting and refitting wheel hubs and associated brake components.
