For sure it's from the boot/fitting area and not the weep hole in the cap? What's your fluid level look like?
As RDTCU said- try to be very certain about the source. Often it's the piston/seal weeping. It's not necessarily common, but by no means uncommon either: http://www.cafehusky.com/threads/te-630-leaking-clutch-master-cylinder.22529/#post-202185 I'm going through the same thing. I have the rebuild kit- just haven't tried it yet. I've read and read on this issue w/ the Magura masters- a lot of it on advrider.com- I'm personally convinced that more often than not it's an issue w/ the cylinder itself (the bore) so rebuilds are often a temporary fix. The kit from Hall's and others will run you around 40 plus 15 for shipping. Easy job- just a little sloppy. Now SilverBullet did find the exact same kit on Amazon for 16 bucks- great deal. EDIT: here's the thread on part #, and how to get one for 16 bucks. http://www.cafehusky.com/threads/anyone-have-a-part-for-our-magura-master-rebuild-kit.40598/
Mine weeps a bit from the top if I don't bleed the master every now and then. As the clutch wears, the neutral position of the slave piston is deeper and deeper, forcing more fluid into the master. When it bottoms out the reservoir membrane, it can force some past the seal and out the weep hole. If it gets to this point, it can also cause your clutch to slip when you drop the clutch quickly.
Thanks. I ordered the one in the Amazon link. Ok I pulled the cap and it appears to be completely full almost to the point of running over.
How should the reservoir membrane look, should it be flat or extended all the way down in the reservoir?
On the TE it's a sort of wedge shape. Look at it closely- you can tell by the way it's molded. I say look closely as mine- early on- had become mis-shapen, so I just popped it back into it's original shape. From there it's pretty easy to gauge how much fluid should be in the reservoir.
Nearly full is too much Sounds like its coming out the weep hole. Mine gets a bit messy after off roading
