Attach friction materials and radius grind


Application

This unit describes the performance outcomes required to attach brake and clutch friction materials using bonding, riveting or screwing methods and radius grind brake shoes. It involves preparing for the task, selecting and attaching friction material, radius grinding, and completing workplace processes and documentation.

It applies to those working in the automotive service and repair industry. The friction materials include those in vehicles from all sectors of the 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 vehicles or 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:

mechanical repair workplace or simulated workplace

workplace instructions

PPE for attaching friction materials and radius grinding

manufacturer specifications and workplace procedures for attaching friction materials and for radius grinding

brake shoes and clutch plate requiring friction material attachment and radius grinding

bonding and riveting materials

radius grinding machinery
