PROBLEMS FACING THE AIR DISC BRAKE FRICTION MATERIAL SUPPLIER

Stability and consistency for better vehicle control, easy maintenance, and weight reduction are cited as advantages for the air disc brake. Problems facing the friction material engineer in supplying pads for heavy-duty air disc brakes are examined: higher energy per sq. in., higher temperatures, need for equal or better life, stronger pad attachment, asbestos elimination (due to worker health concerns), cost effectiveness, risk of an unproven market, and lack of standardization. Satisfactory pad and rotor life and reliable brake hardware are seen as the keys to the success of air disc brakes.
