<p>PURPOSE:To restrain the occurrence of vibration noise and abutting noise by frictional pads, eliminate time loss at an early stage of braking, and thereby letting braking force rise up with its quick response. CONSTITUTION:Each hanger pin installation hole 4j which is formed two by two while being faced to each other in a first and a second arm 4c and 4d, is displaced to a disc turn-out side with respect to both a mounting recessed section 3a in which frictional pads 8 and 8 are housed, and a gap between torque receiving projections 4g and 4g. Elastic members 16 are fitted in the hanger pin installation holes 4j and 4j of the first and second arms 4c and 4d, and each hanger pin 7 is hanged down therein via the elastic members 16. The frictional pads 8 and 8 are suspended a little to the disc turn-out side by the hanger pins 7 and 7, so that the disc turn-out side surfaces 10d of the back boards 10 is elastically brought into contact with the torque receiving surfaces 3c and 4j of the pad mounting recessed section and each torque receiving projection 4g at the disc turn-out side.</p> |
