The other day I got caught in a horrific rainstorm. I got home and cleaned and dried the bike. Then today, a couple days later I notice a drop on my fairing under the front brake resevoir. I go to wipe it off and it takes the paint with it. I noticed some wetness under the resevoir and wiped it all good. No paint or flakes coming off the resevoir. I pumped it a bunch of times and all good no leaks and the resevoir itself is full. I find this odd as I have over 2k on it and this is the first time this has happened, but also the first time I was in rain like that. Any thoughts???

I do know Dot 3 is water soluble, so maybe after a log period of use a slight film developed and rain up behind the front brake lever washed it onto your paint.

That's my story and I'm sticking with it!!! lol

In hoping that was it. The cap seems sealed and the banjo bolt tight. Hoped maybe it was factory buildup that got washed down after the storm. Who knows. If it shows up again then it's an issue.

You said " I got caught in a horrific rainstorm. I got home and cleaned and dried the bike." With all that rain and washing I would not expect any brake fluid film to be left.

I think there is a good chance you have a small leak. Keep a close eye on it.

OK, so just wanted to give an update. Its been almost a thousand miles and not a drop of fluid anywhere. So, I'm thinking because of the intensity of the rain, it might be possible that the water blocked the breather pin holes in the reservoir cap. Then maybe some fluid mixed with water collected under the reservoir and dripped onto the cowling when parked. I don't know, but it's dry as can be.....Though I haven't got caught in a storm like that again neither.

Usually after getting caught in the rain, I use my blower to dry the bike then touch it up with a towel and some cleaner spray. However, I never touched the bottom of the reservoir.

I think you've probably nailed it with this. If it really was leaking you would have noticed by now.

Scary getting caught in those storms! I got caught in one once on my Goldwing where it was raining so hard that there was standing water on the highway! No place to stop or any shelter around so I just plugged along until I got through it. Lol, what a miserable ride that was!
