    I have the front brake reservoir leaking at the cap. Noticed at 700 miles on the bike just after first service. I adjusted the gasket and it seemed to fix it for awhile. It is leaking again. It blows droplets in my face at speed. I ordered a new reservoir since I cannot get just the gasket. ($32). It's a 2018 1290sar.

    Has anyone else had an issue with this? How do you like that fancy quick fix?

    Not that bad but my SAT use to sweet brake fluid when it was topped right up.

    There is an air gap at the top. Seems like the gasket moves a little and causes seepage. Just a little but the air flow its the seepage and blows into my face shield.

    Maybe an aluminum res cap will help?

    I wish I would have thought about that before purchasing the new reservoir.

    I just put the 2nd one on my 1090 today. I looked for an aluminum one but could only find orange. I took the 1st replacement off and cleaned it up and reinstalled it a while back and it worked for a while longer. with the rubber gasket I think I had a tendency to over tighten it. It will hold better if you don’t smash the gasket so far.

    I didn't think I over tightened but I am know to do so. I will double check. Thinks for the input.

    In my ex 1190 the gasket got somehow fluid in to its ”cup” under the cap and blowed fluid from there. Just vlened the hasket and reassembled and was fine since then.
