Course: Automotive Technology II (MLR 3-Year Program) (20104-IIA) > Section: BRAKES: Disc Brakes

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 that a technician discard rather than repair the rotor?
- Where and at how many points does a technician measure rotor for thickness variation?
