Abstract

The present invention addresses the problem of providing a disc brake pad friction material, which is capable of securing fade resistance and wear resistance while satisfying laws relating to copper component content and for which coating by electrostatic powder coating is favorable. As a means for solving the problem, a friction agent composition, which contains 0.3-5 weight % of flake graphite particles of 1-100 μm mean particle diameter with respect to the total amount of the friction material composition as a lubricant and in which the total amount of copper components contained in the friction material composition is less than 5 weight % of the total amount of the friction material composition, is used. Preferably, the flake graphite particles are aggregates. It is also preferable that the friction material composition contains mica with a mean particle diameter of 100-400 μm.
