WARNING: Asbestos fiber dust can be present on brake and clutch assemblies and is hazardous to health if inhaled.
Brake and clutch assemblies must be cleaned using a vacuum cleaner recommended for use with asbestos fibers, such as a brake/clutch/service vacuum. The bag must be labeled per OSHA instructions, sealed, and the trash hauler notified as to the bag's contents.
If a vacuum suitable for asbestos is not available, cleaning must be done wet. If dust generation is still possible, technicians must wear government-approved toxic dust purifying respirators.
The Occupational Safety and Health Act (OSHA) requires areas where asbestos dust generation is possible to be isolated and posted with warning signs. Only technicians performing brake or clutch repair are to be present in the area.
1. Using the special tool, measure the brake drum inside diameter.
2. Adjust the rear brake shoes and linings.
^ Rotate the brake adjuster screw until the rear brake shoes and linings touch the tool.
