Claim 8:
9. A method for forming a friction material comprising:
mixing a fibrous base material and filler particles to form a substrate; saturating the substrate with a silane solution including a silane to form a uniformly impregnated silane matrix;
curing the uniformly impregnated silane matrix to form a cured uniformly impregnated silane matrix;
saturating the cured uniformly impregnated silane matrix with a non-silane binder solution to form a uniformly impregnated silane, non-silane matrix; and
curing the uniformly impregnated silane, non-silane matrix to form the friction material,
wherein the filler particles comprise a friction modifier, the friction modifier comprising an oleophilic tail portion with 10-24 carbons and an active polar head group portion.
