A) Consultation with customers B) Manufacturer specifications C) Consultation with supervisors/managers 2. Read the following information and answer the given questions: Every automotive service workplace has its organisational policies and procedures. These policies and procedures align with the legislative requirements and industry best practices. All the employees are required to follow these procedures. Identify any three best practices and procedures that must be followed while performing the following activities. You will identify any two best practices for each of the mentioned activities. Activities Best practices and procedures Examination of tools and equipment Storage of equipment Identification of the faulty equipment Tagging of faulty equipment Tagging of faulty equipment Disposal of waste Recycling process Workplace documentations 3. Read the given information and answer the following questions: ADR refers to the Australian Design Rules, establishing standards for vehicle safety, theft and emissions. A.) Complete the given table with the information on where the given ADR can be applied to: ADR 35 ADR 38 B.) There are variations in the characters and the braking system features used worldwide. The Australian trailer brakes are more like the North American brakes than European ones. Arrange the given characteristics and features in the appropriate group: • Adaptive brakes • Non-adaptive brakes • Powerful front axle brakes • Disk brake • Drum brake • Predominance valve • No electronics ADR 35 ADR 38 ms 4. Work health and safety revolves around managing all possible hazards and creating a safe environment for all the team members, customers and other stakeholders. Identify the methods for conducting the given task effectively in the workplace whilst following all the work health and safety practices Tasks Safe work practices (Any two for each task) Dealing with stored energy in springs and high-pressure systems Management of brake dust Remove wheel assemblies Refitting wheel assemblies Feedback: S NS 5. Repairing, replacing, and cleaning with heavy vehicle air braking systems produces waste products that adversely affect the environment. Several environmental requirements are put in place by local, state, and federal governments outlining the methods to deal with these hazardous waste products. A.) Rearrange the following environmental requirements in group A to match the associated methodologies in group B. Group A Group B Water quality management Adequate management of equipment like compressors Bunding Check and clear storm drainage Air quality management Decrease the engine run time Noise management Use of appropriate wash bay to avoid destruction of property B) Complete the table documenting the step for trapping, storing and disposing of the following waste products Group A Group B Waste materials Methods Trapping Storing Disposing Brake dust Brake fibres Defective components 6. The heavy vehicle air braking system is composed of different components working together to bring the vehicle to a halt from motion. A.) Provide a brief description of the methodology for an air brake system operation. B.) Identify any one role of the following equipment/process for operating an air brake system. Equipment/ Process Role Levers Friction Pneumatics Electronics A) B) 7. Read the given information and answer the following questions: Below is a list of all the essential components/functions/processes for a heavy vehicle air brake system. Rearrange the essential components/functions/processes given in Group A with associated function and purpose in Group B Group A Group B Disc braking systems Remove moisture from air brake systems Drum braking systems Conversion of the pneumatic energy to the mechanical energy Air compressors storage and compressors It helps in the prevention form the wheel lockup Air dryers Maintain appropriate shoe to drum clearance without manual intervention Brake actuators Switch and maintain the airflow towards the brake pad Foot valves Lever used to convert liner force, so the air chamber pressure push rod which rotates the brake camshaft resulting in the braking force Air control valves Control the flow of air to the heavy vehicle and trailer systems Manual slack adjusters Draw in the atmospheric air and pressurise it into in smaller place Automatic slack adjusters All the braking elements are within brake drums; brake fluid presents pressure to the pistons pressing brake linings which presses the rotating drum slowing down the vehicle Trailer brake valves Supply the compressed air to the braking system for the trailer Pneumatic and electronic control circuits and valves Use callipers to squeeze brake pads against the rotor creating friction and bringing the vehicle to halt Group A Group B Disc braking systems Drum braking systems Air compressors storage and compressors Air dryers Brake actuators Foot valves Air control valves Manual slack adjusters Automatic slack adjusters Trailer brake valves Pneumatic and electronic control circuits and valves Feedback: S NS 8. The first step of any repair procedure is to perform correct diagnostics. It helps to identify the status of the component and root causes of any issues. Identify the diagnostic testing procedures on heavy vehicle air brake systems for different conditions mentioned below: Conditions Diagnostic procedures Wear and tear of frictional materials Drum brake component serviceability Disc brake component serviceability Air pressure testing Air control system testing Air brake component inspection and evaluation Brake system stationary performance tests 9. After performing the diagnostics process, it is necessary to take appropriate actions to bring the air brake system back to normal and safe levels of operations. The actions can include repairing or replacing the system component. The table below indicates the major components of air brake systems. Complete the table with information on the appropriate procedures for removing, replacing or repairing these components. Components Procedures to remove Procedures to replace/ adjust The wheel end section of disc braking systems The wheel end section of drum braking systems Air compressors Air storage tanks Air dryers Brake actuators Foot values Manual slack adjusters Automatic slack adjusters Trailer brake valves Pneumatic and electronic control units/valves 10. Read the given information and answer the following question: The last step of performing the diagnostics and maintenance processes is to conduct post-repair testing. Give a brief description of the following testing methods: • Testing of the service brake • Testing of the emergency brake • Stall testing of the secondary brake • Dynamic performance testing
