Abstract

The present invention provides a friction material for a disc brake pad, which is able to suppress chipping of an edge of the friction material that occurs under the high speed and high load braking conditions and further to suppress the deterioration of the braking effectiveness under the high speed and high load braking conditions while satisfying laws and regulations relating to the required amount of the content of the copper component. A friction material composition that contains 0.5-10 weight % of a resilient graphitic carbon particle relative to the total amount of the friction material composition as a carbon type lubricant and contains the total amount of a copper component contained in the friction material composition is less than 5 weight % relative to the total amount of the friction material composition.
