ABSTRACT:
To provide, without increasing the number of manufacturing steps, a friction material that can effectively inhibit water fade, provide good brake effectiveness and a good wear resistance, and give low aggressiveness against the mating surface. In the friction material comprising the inorganic abrasive material and lubricant, the inorganic abrasive material includes 0.5-10 volume % of the inorganic particle relative to the total amount of the friction material, with Mohs' hardness of 5-8 and the average particle diameter of 0.5-10 μm, and the graphite and the petroleum coke in amount of 8-15 volume % relative to the total amount of the friction material. Proportion of the graphite and the petroleum coke is 2:8-3:7 volume ratio, and the average particle diameter of the petroleum coke is 400-900 μm.
