<p>PURPOSE:To prevent lining from uneven wear when one of a plurality of pistons urging the lining of a brake pad against a disk plate is operated. CONSTITUTION:Lining 16b attached to a back plate 16a of a brake pad 16 is separated into two, and a recess 26 or gap corresponding to the position of a central piston 21 of three pistons 20, 21, 22 is formed between both lining 16a. When the central piston 21 is operated, an working force of the piston 21 is dispersed left and right by the recess 26 or gap to act on a disk plate 18, so that the lining 16b is prevented from uneven wear.</p> |
