Final answer:
Using compressed air to clean brake dust from brake shoes is false. Wet cleaning methods are recommended to prevent health risks associated with inhaling asbestos fibers found in brake dust.
Step-by-step explanation:
The statement that dust from brake shoes should be blown off parts with compressed air is False. It is not recommended to use compressed air to clean brake dust off of parts because brake dust can contain harmful asbestos fibers and other toxic materials. When inhaled, asbestos can cause serious respiratory issues and other health problems. A safer method is to use a wet cleaning process that prevents the dust from becoming airborne.
Proper precautions and methods for handling brake dust are critical for the health and safety of automotive technicians and the environment. The Occupational Safety and Health Administration (OSHA) provides guidelines on how to safely handle brake and clutch dust to avoid exposure to asbestos.
