Course Code and Name: AUR30620 Certificate III in Light Vehicle Mechanical Technology Unit Code: AURLTB103 Unit Title: Diagnose and repair light vehicle hydraulic braking systems You are working in an automotive workshop. Four (4) clients have brought in four (4) different ve- hicles that require diagnosing and repairs to the vehicle hydraulic braking systems. Your assessor will be acting as your supervisor and delegate work to you. The work will be delegated to you from your supervisor (trainer/assessor) as per the activities listed in this assessment task. The description of the activities is mentioned below. You must diagnose and repair the following vehicle hydraulic braking systems faults: · two different light vehicle four-wheel disc hydraulic braking systems, in which the work must involve removing and refitting or replacing the brake callipers, disc pads and disc rotors. · one light vehicle with rear drum braking system, in which the work must involve removing and refitting or replacing brake drums, brake shoes and wheel cylinders. · one light vehicle brake master cylinder, in which the work must involve removing and refit- ting or replacing the brake master cylinder. You must also carry out diagnostic tests in each of the above tasks for at least one (1) of three (3) ad- ditional vehicle hydraulic braking systems faults. You will be testing for one of the following: mal- functioning master cylinders, contaminated brake fluid or worn brake pads. Your supervisor will ad- vise you which diagnostic test you will be required to perform on the vehicles. The role of the supervisor (trainer/assessor) is to allocate the tasks, activities and responsibilities you will be required to undertake to complete these assessments. Your trainer/assessor will also ob- serve you when you are completing the activities and evaluate your performance based on bench- marking in the performance checklists. You are required to source a testing strategy to diagnose and repair the vehicle hydraulic braking system faults in the vehicles. After each activity, you will find a Performance Checklist. The list outlines the tasks you need to per- form, and your supervisor (your assessor) will observe. These assessment tasks are given to you as repair orders. You need to: • Determine the job requirements according to your customer and or supervisor’s instruc- tions. • Access and interpret the technical procedures and information for the diagnosis and repair. • Analyse diagnostic options and source the testing strategy • Identify hazards and environmental issues associated with the work and manage risks. • Select and check tools, equipment, and materials for serviceability. • Inspect the vehicle hydraulic braking systems components for signs of damage. • Test the hydraulic braking control systems. • Compare the inspection and test results with the manufacturer’s specifications. 286ec6b56e3412bb019aa77a526b46d640f1e623.docx 1 Imagine Education Practical Assessment Part B

• Identify faults from the test results and determine the causes of the faults • Confirm and report the cause of fault • Develop and report recommendations for repairs • Source any required information for the repair activity • Gather and check the tools, equipment and materials required for the repair • Complete the repairs • Carry out post-repair testing. • Make final inspection. • Clear the work area. • Process workplace documentation. You need to read the supervisor’s instruction on the repair order underneath, discuss the tasks listed with your supervisor for clarification and fill the vehicle’s details and other information on top of the repair order before commencing work on the hydraulic braking systems. You must also fill out the following documents: • The Testing Strategy Template outline the test strategy you are going to perform. • The Inspection Report to record the outcomes of your testing. • The Post-Repair testing template • Finalise the information on the Repair Order. 286ec6b56e3412bb019aa77a526b46d640f1e623.docx 2
