I saw some wetness under the end of the sheath, and I cut the sheath about a inch from the end, peeled it back, and saw some wet. But the wet may also be brake fluid that got there when I was bleeding the system. It was a little messy. After I lost brakes while riding, I got home, and saw no indication of leakage anywhere. And, I might add, I took the bike out the next day, to make sure it was still doing it, and it was, with the same pressure in the handle, about 80% less. So at this point, the bulging hose scenario is my best bet, but hoping to get the bike to the dealer, and have them look into it themselves.You mentioned that you found brake fluid under the soft rubber sheath, so there is a leak somewhere. It is possible that it is just a pin-hole leak which still provides some braking perssure.
It is also possible that the nut holding the pipe to the ABS pump is loose or cracked and is now leaking fluid.
A bulge will reduce brake pressure but will not leak brake fluid.
CB, don't you have a 2019 N1K ??
If you do, then I would be telling the Dealer and/or Kawasaki HQ that there is a potential safety hazard with you newist bike and that they would be held responsible in the event of an accident due to brake line failure.
The front brake hose, from the ABS pump to each caliper is a single "3 pipe" assembly. You can't just replace the hose on one side.
I spoke with the dealer in Oregon I bought it from, but 7 hrs away, and they will not come and get it, (understandable). My dealer service dept opens tomorrow. No pressure in system now, since I pulled the lines, then rehooked them up. And filled it. But when the event ocurred, I could pull the brake lever almost all the way in, and the brakes would apply gently. Never tried to see if it would eventually go all the way to the throttle, but I suspect it would not, and maintain some pressure. That's why I'm thinking bulge in a line, or less likely a master cyclinder problem. All speculation now. Will be calling a lot of dealers tomorrow, who open on Tues.Bob, no clue how this will play out for you but hope the best. Question can you pull the lever to the grip? And does the pressure bleed off?
I personally had a good experience with Kawasaki over a rear brake line. It broke where the hard line section comes off the banjo bolt on the rear master cylinder.
I had purchased the extended warranty and figured it would be covered under that. Kawasaki America (they made sure to say that for some reason) choose to cover the cost as long as they could have the hose.
