Description Reviews MINI Cooper S Clutch Slave Cylinder Line for all Gen 1 cars, R52/R53. Connects from the output cylinder (slave cylinder) to the main clutch fluid pipe that connects to the flex pipe on top of the transmission. The only see this line fail for two reasons. One being that the car in in the northern states that see rust and the line gets stuck inside the slave cylinder and has lots of rust built up around it and it breaks off. The other was this line fails is when you remove the slave cylinder, the small o-ring like seal comes off the end and is still in the slave cylinder and you fail to see that and you throw out the part to never bee seen again. You can not buy the seal unless you buy the whole line. That seal is required to keep things from leaking. Brand new OEM part so you know that it will fit the first time!
