Modification History

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.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

principles of friction and heat as applied to braking systems

function of the components of a variety of braking system types and arrangements

typical applications of different types of braking systems

requirements of relevant regulations as applying to mobile plant braking systems

tools, techniques and equipment used to remove and dismantle braking system components

procedures for:

checking braking systems for compliance with regulations

measuring brake operating dimensions recording brake operating dimensions

checking braking system operation

removing and dismantling braking system components

cleaning braking system components and solutions to be applied

adjusting brake clearances, levers, linkages and pedal clearances

checking for hydraulic, air and vacuum system leaks and restrictions

testing and recommissioning the braking system

worn and defective friction materials

specifications of the braking system

corrective action to be taken when brake operating measurement varies from specification

corrective action to be taken when faulty braking system components are identified

characteristics of surface finishes and wear patterns as applied to braking system components

reasons for identifying the components for reuse or replacement

precautions to be taken when handling braking systems components

reasons for selecting the chosen tools, techniques and equipment

tests, tools, techniques and equipment required to test the braking system and reasons for selection.

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 replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or 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

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
