Automotive brake linings used nowadays are a complex composite of organic resin binder, asbestos fiber reinforcement and friction modifying fillers. This paper investigate the dependency of the tribological properties, mainly, the co-efficient of friction, the wear rate, and the fade temperature on the constituents used to formulate the linings. Seven formulations were produced with different asbestos/resin content ratio. The tribological properties were measured. The drag dynamometer results showed that the fade temperature and the. wear rate increases as the asbestos content increases. The coefficient of friction of low asbestos content varies initially from 0.2 to 0.25 but it decreases rapidly to 0.1. For high asbestos contents, the coefficient of friction was appeared to be erratic.
