Application
This unit describes the performance outcomes required to diagnose and repair faults in the braking systems of motorcycles. It involves preparing for the task, selecting the correct diagnostic procedure, carrying out the diagnosis and the repair, performing post-repair testing, and completing workplace processes and documentation.
It applies to those working on motorcycles in the automotive service and repair industry.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

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 motorcycle braking systems 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:
motorcycle repair workplace or simulated workplace
workplace instructions
manufacturer motorcycle braking system specifications
two different motorcycles with faults in the braking systems specified in the performance evidence
diagnostic equipment for motorcycle braking systems
tools, equipment and materials appropriate for repairing motorcycle braking systems.
