Hi all,



Spent part of my afternoon cleaning, detailing, and doing some maintenance on both the TW's today and we noticed that our 2010 master cylinder was starting to leak in the exact same place as the leak on the older 05, who's damage is more pronounced because it's been there longer.



So here's the leak on the 2010 just starting to happen...







And here's what it looks like on the 2005...







So if I do nothing to the 2010 to stop this, it will look like this 2005 picture in relatively short order, since I have actually put about 1000 more miles on the 2010 then what is on the 2005 at this point. (The new one is under warranty, so I've been beating the poop out of it... er... I mean testing)



So, is this happening to a lot of our TW's, or did I just get the two that need to have these seals replaced?



Someone know the how to make it stop for good?



Thanks in advance!



Rory

Same issue on my 2010. It looks like the metal in your picture has corroded a little bit? It just looks like the paint is peeling off of mine.

Top one is the 2010, and the paint is peeling. If left alone, it will look like the second picture, which is the 05. Hoping to stop it now.



I don't see any actual brake fluid leaking on either bike, it's more like it's seeping out.

My '05 does not have this paint peeling/chipping problem due to seepage or leak issue. Is there any kind of anti-corrisive coating that can be applied to prevent this, assuming the seepage problem is solved?

I'm def going to show these pictures to the dealer when I bring the 2010 in to have them look it over. I'm assuming this is covered by the warranty since brakes are sort of a"safety" item.

Aluminum Jelly, perhaps?

Is there a chance that they are over filled?



Try bleeding at the connections too. I always find a little air in the banjo bolts

I talked to the dealer today and they seem to think it is overfilled or has a bad gasket. He wants to just sand and repaint but I think that may just be masking the problem until it comes back. Guess i'll just have to wait and see

I am sorry to see that you had to consult with the dealer for this.

I'll let the dealer fix the one under warranty too, since if it's over filled, they did it. It needs to see the dealer once before the warranty expires anyway. The 05' is on me, so I'll have to open er up and see what I'm dealing with from the inside.



Thanks for the input, folks

How do you bleed the banjo bolts? Just unscrew a turn or two while holding the brake lever gently?

Does any rider have an answer for the aforementioned post(s) ?. I'm having the same issue on my 09....2,000 miles....brake was bled 3 years ago....no signs of leakage ,but the damn paint is peeling off ?. I'm going to bleed them again and replace the diaphram .
