Disc Brake System: Description and Operation

WARNING: Asbestos fiber dust may be present on brake and clutch assemblies and is hazardous to health if inhaled.

Brake and clutch assemblies should be cleaned using a vacuum cleaner recommended for use with asbestos fibers such as Brake/Clutch/Service Vacuum 164-R3600 or equivalent. The bag must be labeled per Occupational Health and Safety Act (OSHA) instructions, sealed, and the trash hauler notified as to the bag's contents.

If a vacuum suitable for asbestos is not available, cleaning should be done wet. If dust generation is still possible, technicians should wear government-approved toxic dust purifying respirators.

Grinding or sanding brake linings, pads, rotors, drums or clutch facings should be performed using properly exhaust-ventilated equipment.

Occupational Health and Safety Act (OSHA) requires areas where asbestos dust generation is possible to be located and posted with warning signs. Only technicians performing brake or clutch repair should be present in the area.
