Description Reviews MINI Cooper S Clutch Slave Cylinder Line Seal for all Gen 1 MINI Cooper S's, R52/R53. Connects the output cylinder (slave cylinder) to the main clutch fluid pipe that connects to the flex pipe on top of the transmission. We only see this seal "fail" when you throw out the slave cylinder out and do not realize that the seal is still in the slave cylinder... never to be seen again. You cannot normally buy the seal unless you buy the whole line (which some times is a good idea if there is lots of rust on it). That seal is required to keep things from leaking. We have now found a way to buy they seal in packs of 2 and split them up to help you save money since you only need 1! Besides, you're going to buy other things at the same time! Give us a call if you have any questions. Don't forget some quality brake fluid! 1 Review 5 Makes a seal! Posted by Jacques Gordon on 8th Nov 2022 Fixed they no seal condition from they line to the salve cyl with out having to buy they whole line. Thanks DT for finding they small items!
