The pad (1) comprises a base plate (2) and a plurality of friction elements (4) fixed to the base plate (2). The friction elements (4) comprise first friction elements (4b) made of a first material and second friction elements (4a) made of a second material. The second material has a compressibility modulus (pressure needed to compress the material by 1 mm) smaller than the one of the first material of a value equal or greater to 5 MPa. There is a greater number of the first friction elements (4b) than of the second friction elements (4a) .",
