• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Is there a rebuild kit available for the front master cylinder? There looks to be a piston and some o-rings in the parts book but its listed as a Pin. When you pull the lever it grabs and then keeps going to the handle bar it won't hold pressure and I see no fluid leaking any where.

I had the same problem with my 125 and purchased the master cylinder rebuild kit and the caliper rebuild kit from partspitstop.com. I replaced the O-rings in the caliper first and that solved the problem, never rebuilt the master. There are two o-rings on each piston and you basically pump the lever until both pistons come out of the caliper at the same time, replace the o-rings, put the pistons back in the caliper then re-bleed the brake. In my case, the o-rings got worn by dirt/sand and started to let air into the system. I believe most KTM's EXCs use the same brembo brakes as yours with 28mm pistons. Here is a link to the caliper parts for a 2003 250exc, hope this helps:

Thanks, I'll bleed it out and see if the problem still is there, then order the parts.How's the 167 running I missed the gathering part 2.
 
You could also try the trick of tying the brake lever all the way in and leave it overnight. This helps short term. I really like the 167, it's perfect for how I like to ride.
