Abstract:
Provided is a friction material composition capable of giving friction materials which, although low in copper or copper-alloy content, have excellent fade resistance at high temperature and give a satisfactory pedal feeling during braking. The friction material composition has a binder, a fibrous base material, an inorganic filler, and an organic filler, and contains no copper or has a copper content of 0.5 mass or less. The inorganic filler contains two γ-alumina powders, i.e., a first γ-alumina powder, which has a median diameter (D 50 ) of 0.8-60 μm, and a second γ-alumina powder, which has a median diameter (D 50 ) of 80-400 μm.

Claim (Index 3):
The friction material composition as set forth in  claim 1 , wherein a difference in the median diameter (D 50 ) between the first \u03b3-alumina powder and the second \u03b3-alumina powder is 139 to 305 \u03bcm.
