515系(xi)列制動器(qi)被稱為浮動卡鉗。它們的(de)尺寸(cun)相對(dui)緊湊，卡鉗一(yi)側的(de)襯里是固定的(de)，而(er)另一(yi)側的(de)襯里則驅動提供(gong)夾(jia)緊力。因(yin)此，必須允許(xu)515系(xi)列制動器(qi)在安裝銷或肩(jian)螺栓上滑(hua)動，以(yi)便它可以(yi)在旋轉(zhuan)的(de)制動盤上自對(dui)準，并(bing)從兩個襯片上為轉(zhuan)子提供(gong)相同的(de)夾(jia)緊力。

機(ji)(ji)械(xie)應(ying)用(yong)(yong)(yong)(yong)設(she)(she)(she)計(ji)(ji)使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)機(ji)(ji)械(xie)杠桿和凸輪系統來施(shi)加和釋放制(zhi)(zhi)動(dong)(dong)器(qi)。這種設(she)(she)(she)計(ji)(ji)可以使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)直徑(jing)(jing)為(wei)6英(ying)(ying)寸(cun)(cun)或(huo)更大的(de)5/16至1/2英(ying)(ying)寸(cun)(cun)厚(hou)的(de)轉(zhuan)子(zi)；液(ye)(ye)壓設(she)(she)(she)計(ji)(ji)使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)調制(zhi)(zhi)液(ye)(ye)壓源，例如(ru)主(zhu)(zhu)缸，來控制(zhi)(zhi)制(zhi)(zhi)動(dong)(dong)扭矩(ju)。這些制(zhi)(zhi)動(dong)(dong)器(qi)使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)直徑(jing)(jing)為(wei)1 1/2英(ying)(ying)寸(cun)(cun)的(de)致動(dong)(dong)活塞。它們被設(she)(she)(she)計(ji)(ji)成(cheng)與3/8至1/2英(ying)(ying)寸(cun)(cun)厚(hou)的(de)轉(zhuan)子(zi)一起使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)，其直徑(jing)(jing)為(wei)6英(ying)(ying)寸(cun)(cun)或(huo)更大；彈簧應(ying)用(yong)(yong)(yong)(yong)，液(ye)(ye)壓釋放設(she)(she)(she)計(ji)(ji)使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)一堆貝氏(shi)彈簧從主(zhu)(zhu)缸等來源施(shi)加制(zhi)(zhi)動(dong)(dong)和液(ye)(ye)壓以釋放制(zhi)(zhi)動(dong)(dong)器(qi)。該設(she)(she)(she)計(ji)(ji)可與5/16至1/2英(ying)(ying)寸(cun)(cun)厚(hou)的(de)轉(zhuan)子(zi)一起使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)，其直徑(jing)(jing)為(wei)6英(ying)(ying)寸(cun)(cun)或(huo)更大。
