Release 1. Supersedes and is equivalent to MEM18035B Diagnose and rectify braking systems

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

  • following work instructions, standard operating procedures (SOPs) and safe work practices, including brake dust, fibre and fluid control and protection procedures
  • identifying and interpreting specifications, charts, lists, drawings and service documents to diagnose and rectify braking systems
  • checking braking system for conformance to specifications and for compliance with relevant regulations
  • checking friction materials and identifying as being serviceable or to be replaced
  • undertaking calculations and numerical operations for diagnosing and rectifying braking systems
  • measuring and recording brake operating dimensions and identifying variations of brake operating measurement from specifications
  • checking operation of braking system for compliance to specifications and identifying faulty components for replacement
  • checking braking system interaction with equipment control and recording systems and components
  • removing, dismantling, handling and replacing braking system components safely
  • cleaning components using appropriate solutions and safety precautions
  • adjusting brake clearance, levers, linkages and pedal clearances using appropriate tools, equipment and procedures
  • testing and recommissioning the braking system for compliance with specifications/regulations.

Assessment Conditions

  • Assessors must:
  • have vocational competency in diagnosing and rectifying braking systems at least to the level being assessed with relevant industry knowledge and experience
  • satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacementand comply with the National Vocational Education and Training Regulator Act 2011, its replacementor equivalent legislation covering VET regulation in a non-referring state/territory as the case requires
  • Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills
  • Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications
