    Hey, rebuilding the master is duck soup even Kevin can do it.... Changing a line is simple too if you have the vacuum bleeder. Why not try it and maybe you will surprise yourself and get more confidence and know your dog better... You can still ride with just a rear brake just take it easy..... I rode a chopper for years without a front brake... and a custom for a year without a back brake...

    Bill, you make me want to try it. However, I have a lousy track record when it comes to fixing things in general. I might give it a try..I always wind up losing something or breaking it. I hate not being able to do it myself, so your right I should give it a try but it sounds like it will be any number of things. Even with the Master, if its not leaking, which it never has before, I don't see where the air would get in since as you point out it is a closed system. However, in the end result your story of what you went through to finally get your problem solved says that it could be any of the components. So if I understand you I should start with the master and then the line itself. Thanks for your help..Tony

    There is a vent hole in the cover, right behind the mirror stem, and if the seal is gasket is bad the leak could be coming from there

    Rebuild the master, rebuild the caliper. Both very easy and cheap. Then refill and properly bleed it. $53 worth of parts.

    Master: http://www.wildsteedworx.com/index....ath=65_68_173_74_273_320_321&products_id=1530
    Caliper: http://www.wildsteedworx.com/index....ath=65_68_173_74_273_320_322&products_id=1179

    If you can't rebuild these yourself your shop certainly can. Find the dropbox link for the 08 service manual and you'll see how to do it. If not maybe another member lives near you and can help?

    Yes it is a sealed system but i had the exact same problem not to long ago. Long story short, it was not a simple find. I found out that the PM calipers you can split them to do a rebuild, which is only 4 piston cup seals and 2 very small "O" rings. That was the problem, the 2 "O" rings in between the calipers when you split them apart, on one half there is a recess and small hole and other one is just a small hole. that's how the fluid passes between the halves. My calipers have never been split apart but the "O" rings wore out and seeped. As said by one of the other posters, no matter how small a leak or seep, if it comes out, air gets in. Sorry for the long post, JMO
