Patent ID: 8522932

Claim:
A disc brake pad for a disc brake, equipped with a ferrous disc rotor, having a friction material comprised of: (A) a fiber base material, (B) a binder of 4.5-7.0 weight % relative to the gross friction material amount including aralkyl modified phenolic resin of 50-80 weight % relative to the gross amount of the binder, and 2,000-5,000 weight average molecular weight of phenolic resin except said aralkyl modified phenolic resin as a remainder of the binder, (C) an abrasive material including inorganic particles of 1-3 weight % relative to the gross friction material amount, where said inorganic particles have Moh's hardness between 6 and 8 and average particle diameter of 10-200 μm, and (D) a frictional wear modifier.
