ABSTRACT:
To prevent local abrasion of a lining of a brake pad when one of a plurality of pistons for pressing the lining against a disk plate is rendered operative, a lining 16b mounted on a back plate 16a of a brake pad 16 is separated into two, and a recessed portion 26 or a gap is formed between the two linings 16b in a corresponding relationship to the position of a central one 21 of three pistons 20, 21 and 22. When the central piston 21 is rendered operative, the operating force of the piston 21 is dispersed to the left and right by the recessed portion 26 or the gap to act upon a disk plate 18, and consequently, local abrasion of the lining 16b is prevented.
