<p>A brake pad (10; 20; 30; 40; 50; 60; 70; 80; 90) has its backing plate (24; 32; 36; 42; 54; 86; 96) flexible in regions thereof which are adjacent to the leading and trailing edges (16; 18) of a block (12) of friction material carried on the backing plate. This flexibility reduces thermal stress so that cracking is less likely. The flexibility may be achieved by a reduction in thickness which may be achieved by chamfers (28), steps (34; 38; 66; 68; 92) or grooves (44; 64; 82).</p> |
