SAFETY TIPS
Do not breathe brake dust when performing brake inspection or repair work. Some old brake linings contain asbestos, which can cause health problems. Never clean brake dust with compressed air or a brush. Use a dampened rag instead. If you are working on brakes that have asbestos linings, wear a high-efficiency dust mask suitable for the purpose and take additional precautions to avoid breathing the dust. Finally, use non-asbestos or semi-metallic replacement linings if possible.
