   • Hazards associated with the work are identified and risks are managed
   • Dismantling tools and equipment are selected and checked for serviceability
2. Dismantle and evaluate braking system components
   • 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
   • Components are cleaned for evaluation according to workplace procedures and safety and environmental requirements
   • Components are measured and compared with manufacturer specifications and serviceability is determined
   • Component repair method is determined
   • Unserviceable parts are identified and replacement parts sourced
3. Carry out overhaul
   • Overhaul information is sourced and interpreted
   • Overhaul options are analysed and those most appropriate to the circumstances are selected
   • Overhaul tools and equipment are selected and checked for serviceability
   • 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
   • Components are assembled according to manufacturer specifications, workplace procedures, and safety and environmental requirements
   • Tolerances and clearances are measured against manufacturer specifications and necessary adjustments are made
   • Assembly of components is completed within workplace timeframes and without causing damage to other components or systems
   • Post-assembly testing is carried out according to workplace procedures and safety and environmental requirements, and any problems detected as having been introduced during the assembly process are rectified
5. Complete work processes
