    Hi Rick B, thanks for the video. I will dismantle my callipers this week and see if they have the same problem.


    !Why would you even consider dismantling your calipers when the bike is brand new and under warranty! Surely if this concerns you, you should be beating your way to your dealer's door?

      Hi Bandytales,


      The reason being that my dealer has already changed the calliper and the problem persists. I would like to know if the calliper pistons are leaking brake fluid, which means that BMW is not only installing faulty brake callipers from factory but is also supplying faulty brake callipers as replacements.

        So why not take the bike back to them with the dirty marks?

          That is a bit of a leap thinking they are fitting faulty replacement callipers, nobody else who have had the callipers replaced have had the same problem again. What does brake dust have to do with leaking callipers. If the callipers are leaking, you will see the fluid, its wet. Brake dust doesn't come from leaking callipers.

            That's the thing, I checked the interior of the replacement calliper with tissue paper (which is very absorbant) and it came out with brown brake fluid stains mixed with black brake dust. Seems to me that there must be some sort of leakage inside the calliper.

              I would take it back to your dealers then, but if you do take the calliper off, take some pics if there is a leak. Like I said, I have seen no reports on any other forum or facebook of a replacement calliper leaking on any GS GSA or RTs, so this is potentially very worrying for those that have had replacements.
