    Default Brake fluid leak rear? 2013 RS-S

    Noiced this after a hot ride (about 90 deg. for an hour). Seems like brake fluid. Is this a normal overflow? Seems about a tablespoon or so. Wasn't hot or anything. Reservoir looked fine. Have not received a "brake failure" warning message (though I had one in the winter and added, ironically, a tablespoon). Reservoir is not topped-off under seat. Source seems to be coming from in front of the shock.

    It's weeping out of the reservoir caps. Better clean it up real good because it will ruin the paint on the frame.

    Default Here's the thing..!!

    Recently had a similar problem. Seems the caps have a breather hole and need to be positioned to the high side. ( towards the back ) also the level is sensative and if overfilled will leak down the front of the resivoir and on down as you showed. I now tuck a folded paper towel in the forward section to make sure it doesen't run down there...

    Ah! There was a bit of fluid there. That reservoir is quite pesky. The sensor indicates LOW and BRAKE FAILURE in the winter because of the fluid compressing ever-so-slightly! I'll re-position and try to find the hole. Easy. THANKS GUYS!

    Quite a paint eating repeat error when they prep or work these, the rubber underside of the cap has a vent slit that needs to be rotated near the raised plastic bump on the top side. It can be aimed more aft than that bump on the top.
