The method comprises contacting the friction material with an aqueous solution comprising at least about 0.05 weight alkanolamine-carboxylic acid salts being the reaction product of:, (i) alkanol amine; and, (ii) C4-C20 carboxylic acid; and thereafter evaporating water from the aqueous coating on the friction material so as to leave the friction material with a coating comprising alkanolamine-carboxylic acid salts. Friction materials coated by above method are also claimed.
