Performance Criteria 

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section.

1. Prepare to dismantle air braking system components

1.1 Job requirements are determined from workplace instructions

1.2 Dismantling information is sourced and interpreted

1.3 Dismantling options are analysed and those most appropriate to the circumstances are selected

1.4 Hazards associated with the work are identified and risks are managed

1.5 Dismantling tools and equipment are selected and checked for serviceability

2. Dismantle and evaluate air braking system components

2.1 Braking system components are dismantled in a logical sequence according to manufacturer and workplace procedures, and safety and environmental requirements , and without causing unnecessary damage to components or systems

2.2 Components are cleaned for evaluation according to workplace procedures and safety and environmental requirements

2.3 Components are measured and compared with manufacturer specifications and serviceability is determined

2.4 Component repair method is determined

2.5 Unserviceable parts are identified and replacement parts sourced

3. Carry out overhaul

3.1 Overhaul information is sourced and interpreted

3.2 Overhaul options are analysed and those most appropriate to the circumstances are selected

3.3 Overhaul tools and equipment are selected and checked for serviceability

3.4 Components are machined, repaired and replaced as required, and adjustments are carried out according to manufacturer specifications, workplace procedures, and safety and environmental requirements, and without causing damage to components or systems

4. Assemble components

4.1 Air braking system components are assembled according to manufacturer specifications, workplace procedures, and safety and environmental requirements
