摘要：
A brake device for a vehicle is provided in which when a slave cylinder (42) generates a brake fluid pressure that is commensurate with the actual amount of operation of a brake pedal (12) by a driver in a state in which a master cut valve (32, 33) is closed and a fluid path connecting a master cylinder (11) to the slave cylinder (42) is cut off, a wheel cylinder (26, 27, 30, 31) is actuated by the brake fluid pressure. Since deterioration determination means (M1) determines a leak in the downstream of the slave cylinder (42) based on the actual amount of actuation of the slave cylinder (42) detected by a slave cylinder stroke sensor (Se) and the actual brake fluid pressure generated by the slave cylinder (42) and detected by a fluid pressure sensor (Sb, Sc), it is possible to rapidly determine a leak in the downstream of the slave cylinder (42).
摘要（中）：
本发明提供一种车辆用制动装置，其中，在从动液压缸（42）产生与驾驶员对制动踏板（12）的实际操作量相称的制动液压时，在主切换阀 （32,33）关闭，并且将主缸（11）连接到所述从动缸（42）的流体路径被切断，轮缸（26,27,30,31）由所述制动液压力致动。 由于劣化判定单元（M1）基于从动液压缸行程传感器（Se）检测出的从动液压缸（42）的实际的工作量和实际的制动液压（P）来判定从动液压缸（42） 由从动液压缸（42）产生并由流体压力传感器（Sb，Sc）检测的情况下，能够迅速地判定从动液压缸（42）的下游侧的泄漏。
