Abstract: Friction block or layer made of an asbestos free friction material, the friction material including, as composing materials thereof, inorganic and/or organic and/or metallic fibers, at least a binder, at least a friction modifier or lubricant and at least a filler or abrasive, wherein the asbestos free friction material also contains, as an additional composing material or additive, an hydrophobic wax, preferably present from 0.5% to 5% in volume, the asbestos free friction material block or layer possessing a hydrophobicity, defined as the time of absorption within the friction material of a liquid drop formed by 20+/−5 μL of distilled water, of more than 60 minutes, so that the force to detach the friction block or layer from a metallic surface to which it has been made to stitch electrochemically is lower than 15 Nw.
