    I have started to make repair kits for BMW R1100S and R1150GS RS R RT hydraulic clutches.

    At some point in the bike's lifetime, the clutch actuation system starts to leak. This is most likely because the clutch fluid has not been changed when it should have been changed. What happens is that the brake fluid level in the reservoir starts to get lower, and it can get to the clutch friction plate, making it slip. This would be the worst case scenario. Usually, the level stays the same, or drops very slow, because as the clutch material wears, the level in the reservoir rizes, and if the seal is leaking, the effects somehow compensate oe for each other.

    The pump does not scratch and the piston has no damage either. Getting the brand new system, as new, is a waste of money IMHO.

    The kit contains:

    - new piston rubber seal;
    - new gasket between the cylinder and the gearbox;
    - new seger C-clip

    The OEM system costs 147$, +/-. Ther repair kit is sold for 55$, shipping included, worldwide!

    Ordering will be available via my webshop, in the signature(shortly).

    Anyone used this kit?

    Mine is definitely leaking at 100k km, not badly and no brown sludge or contamination of the clutch yet. The only thing is a new slave is $319 here.

    Just curious how to take the slave cylinder apart and replace the piston seal. I haven't pulled the slave cylinder out yet; I'd just like to know what to do with it when I get it out. Any grease required, special tools, etc.? Any pics? Thanks.

    Did not get to make a pictorial about this, because my hands are always dirty when changing clutches or actuation.

    To get the piston out, you need the special pliers for the C-clip. Once that one is out, push the clutch lever one or twice and the piston will pop out. There is going to be fluid all over so be ready.

    To get the seal out of the piston, use a tool designed for seal removal. That would be the best recommendation. or a screwdriver that does not have any sharp edges, otherwise you might scratch the piston and that would result in leakages.

    Thanks, Dan. That answers my questions. I hope to do the repair sometime next week. I always intend to take pictures when I do a repair, but often get elbow-deep and forget about it.
