    Rebuild the Brembo Master clutch cylinder

    Cannot find a rebuild kit for the life of me but does anyone on this forum have the size and a source for the seals and o-rings on the ETV1000 clutch master cylinder?
    I found a replacement slave cylinder in Canada and it's on its way but no joy on a master kit or replacement.
    Thanks!

    You mean, how to get the piston out? I don't remember now if there is a Seeger ring or not holding it, but if there is, that's the only thing holding the piston so it should come out easily after removing the circlip.
    The tricky part is to put the new seal back on the piston. And here comes the silicon sealant nozzle trick.

    You guys have short memories. I just went through this recently, and Wemoto has the complete piston with seals installed plus the dust seal reasonably priced.

    Once you remove the lever, remove the dust seal, then the rest of the guts just fall out.

    Mine's fine as I have resealed it some time ago with FPESeals, but I am considering buying it just in case.

    After chasing seals for my Futura "Brembo" Master cylinder I can confirm the following part numbers.

    The actual dimensions of the Master piston/bore it is to fit is 12mm od x 7mm id x 4mm SU12-7-4-EP-DS106 IS CORRECT


    The actual dimensions of the Master piston/bore it is to fit is 12mm od x 5mm id x 4mm SU12-5-4-EP-DS106 IS CORRECT

    The actual dimensions of the Slave piston/bore it is to fit is 28mm od x 20mm id x 4mm wide SU28-20-4-EPDM-DS106 IS CORRECT

    The suppler is FPE Seals Ltd, 7 Barrington Way, Darlington, County Durham, DL1 4WF, England.

    The staff are extremely helpful.
