At this time, the body portion 26 of the locking means connected to the hydraulic chamber 12 is lowered to a negative pressure or below a certain pressure, the elastic force of the elastic member 30 overcomes this and releases the locking of the locking member 28.
이때 가압수단은 탄성부재(34)에 의해 가압부재(32)가 실린더내의 유압을 가압하게되고, 이 가압력을 받는 플레이트(18)는 디스크(4)를 가압하여 패드(22)와 마찰력을 발생시켜 제동작용을 한다.At this time, the pressing means is the pressing member 32 by the elastic member 34 to press the hydraulic pressure in the cylinder, the plate 18 subjected to this pressing force presses the disk 4 to generate a friction force with the pad 22 Braking action.
