Please tell me this isn't a brake fluid leak
I have no idea where that stuff came from. I checked the pipe running to the caliper and its completely clean.
Everything else looks clean except what you see. |

It looks like brake fluid to me. It might be coming out of the master brake cylinder and running down your brake lines to the low spot pictured. Crush washers can fail if the banjo bolt above the brake cylinder is over-tightened. The bad news is that brake fluid spills should be wiped up right away, it can eat through your paint very easily. If your under warrantee, have it dealer inspected so your bake will be fixed and also future paint or swingarm replacement should be covered due to the defect.

Its dark and my camera flash is terrible.
Smells like grease to me. I did a thorough pat down of the brake reservoir pipe - didn't feel wet spots. The exterior of the pipe just above the suspected leak was spotless. I'll keep a close eye over the next few rides to see if its a serious problem. Edit: Time to give it a bath... |

Awesome!! Would have felt pretty down if it was a brake leak.
Especially with all of my recent "ZOMG I'm getting good at riding and treating the bike well" posts. Thanks for the input people. |

Lots of funky things land different places on your bike, make sure ya ain't got a visible leak, clean it off, ride it some more... If it keeps doing the same thing it's a problem. if its a random bird turd, or road grime your good!

If the bike was on the side stand, how could the staff flow up on the top face of the swingarm without some help "from above"?

"Hydraulic hose is graded by pressure, temperature, and fluid compatibility. Hoses are used when pipes or tubes can not be used, usually to provide flexibility for machine operation or maintenance. The hose is built up with rubber and steel layers. A rubber interior is surrounded by multiple layers of woven wire and rubber. The exterior is designed for abrasion resistance...............Hydraulic hoses generally have steel fittings swaged on the ends. The weakest part of the high pressure hose is the connection of the hose to the fitting. Another disadvantage of hoses is the shorter life of rubber which requires periodic replacement, usually at five to seven year intervals." http://en.wikipedia.org/wiki/Hydraul...ipes_and_hoses http://en.wikipedia.org/wiki/Brake_bleeding http://en.wikipedia.org/wiki/Brake_fluid It is commonly called brake line or brake hose. Yours is extra protected by a rubber hose (the surface that you see). The real brake hose can be seen at the end, where it connects to the metal fitting.

If it was brake fluid it would most likely take the paint off when you removed it.
If you thought it was brake fluid, the first thing you would check is the fluid level in the rear mastercylinder. If it was leaking it would let air into the system and the petal would feel soft, but might change when you pumped it repeatedly. If it didn't take the paint off, the lever feels right, and the level in the mastercylinder isn't low - it's not brake fluid. |
