Should dust from brake shoes be blown off parts with compressed air?

Blowing dust from brake shoes off parts with compressed air is not recommended because it can pose several safety and health risks. Brake dust can contain hazardous materials, including asbestos in older vehicles, which can become airborne and be inhaled by the technician or those nearby. This can lead to respiratory issues and other health problems.

Using compressed air can also cause brake dust to scatter and potentially contaminate other components or areas of the vehicle, leading to further issues. Instead, technicians typically use a damp cloth or a vacuum equipped with a HEPA filter to safely remove brake dust without alarming dispersal, effectively minimizing health hazards and maintaining a clean workspace.

The answer reflects an important aspect of shop safety protocols and industry best practices when working with brake components.
