Technician Safety Information

When working on or around brake assemblies, care must be taken to prevent breathing asbestos dust, as many manufacturers incorporate asbestos fibers in the production of brake linings. During routine service operations the amount of asbestos dust from brake lining wear is at a low level due to a chemical breakdown during use, and a few precautions will minimize exposure.
1. Do not sand or grind brake linings unless suitable local exhaust ventilation equipment is used to prevent excessive asbestos exposure.
2. Wear a suitable respirator approved for asbestos dust use during all repair procedures.
3. When cleaning brake dust from brake parts, use a vacuum cleaner with a highly efficient filter system. If a suitable vacuum cleaner is not available, use a water soaked rag. Do not use compressed air or dry brush to clean brake parts.
4. Keep work area clean using same equipment as for cleaning brake parts.
5. Properly dispose of rags and vacuum cleaner bags by placing them in plastic bags.
6. Do not smoke or eat while working on brake systems. Never use gasoline, kerosene, alcohol, motor oil, transmission fluid, or any fluid containing mineral oil to clean brake system components. These fluids will damage the rubber caps and seals. If system contamination is suspected, check brake fluid in the reservoir for dirt, discoloration, or separation (breakdown) of the brake fluid into distinct layers. Drain and flush the hydraulic system with clean brake fluid if contamination is suspected.
