Why has asbestos lining been phased out in clutches?

The phasing out of asbestos lining in clutches is largely due to the health hazards it presents. Asbestos is known to release harmful fibers into the air when disturbed, which can lead to serious respiratory issues and diseases, including asbestosis and lung cancer, upon prolonged exposure. The risks associated with inhaling asbestos fibers have prompted regulatory measures and a shift towards safer, alternative materials.

While cost and performance considerations may also factor into the discussion around clutch materials, the primary impetus behind the change is the well-documented health risks associated with asbestos. Other materials used in clutch linings, such as organic composites and ceramic compounds, not only avoid these health risks but can also offer effective performance, further supporting the move away from asbestos.
