Procedures include using proper measuring tools to determine the condition of the rotor.

Process/Skill Questions:

- What tool is used to check lateral runout and thickness variation?
- What evidence should require a technician to discard rather than try to repair the rotor?
- At how many points does a technician measure rotor for thickness variation?
