The invention relates to a diagnostic system and method for a bicycle disc hydraulic brake system. A diagnostic method for a bicycle disc hydraulic brake system, in particular a master cylinder assembly thereof, comprises: a) providing a master cylinder assembly comprising a cylinder, a piston movable by reciprocating within the cylinder against the action of a return spring, and a hydraulic tank comprising a bottom, a top plate and a membrane, the membrane divides the tank into a variable volume filled chamber and a complementary variable volume empty chamber, the tank being fluidly connected to the cylinder by at least one main passage in the bottom, b) metering means providing the distance of the membrane from the top plate of the tank, c) injecting hydraulic fluid into the master cylinder assembly, d) moving the piston by reciprocating movement within the cylinder, e) evaluating, with the processing means, whether the output signal of the membrane detector device indicates that the temporary proximity of the membrane to the top plate has a degree corresponding to a predetermined proximity range, f) if the evaluation is positive, determining that the master cylinder assembly is correctly operated, and if the evaluation is negative, determining that the master cylinder assembly is not correctly operated.
本发明涉及用于自行车盘式液压制动系统的诊断系统和方法。用于自行车盘式液压制动系统的、特别是其主缸组件的诊断方法包括:a)提供主缸组件,其包括缸、活塞及液压箱,活塞能通过克服回位弹簧的作用在缸内往复运动而移动,液压箱包括底部、顶板和膜,膜将箱分成可变体积填充的室和互补可变体积空室,箱通过底部中的至少一个主通路流体连接到缸,b)提供膜距箱的顶板的距离的计量设备,c)将液压流体注入主缸组件,d)通过在缸内的往复运动来移动活塞,e)用处理装置评估膜检测器设备的输出信号是否指示膜对顶板的暂时靠近具有对应于预定靠近范围的程度,f)如果评估是肯定,确定主缸组件正确操作,如果评估是否定,确定主缸组件未正确操作。
