A friction material, including a fibrous reinforcement, a friction modifier, a lubricant and a binder, comprising a water-repellent fluoropolymer incorporated therein. The further incorporation of an alkaline metal salt makes it possible to render the matrix more hydrophilic and hence reduce creep noise. The foregoing fluoropolymer is one selected from the group consisting of ethylene tetrafluoride polymer, tetrafluoroethylene-hexafluoropropylene copolymer and polyvinylidene fluoride or a combination thereof.
