Unhappy Front brake fluid and Will Be Selling the bike

Mystery
by Jeremy Brown

One cold fall night as I was cruising home from work, it was an average night at 2 in the morning. The cops in the college town paid me no attention as they were focused on getting the underage drinkers and drunk drivers. They have seen my bike leave the school at 2 for months now, as if it were a normal occasion.

OK I will stop the story or rather begin it, I was driving home from work the other day and went to apply the front brakes and what do you know I have a ton of air in the lines and I am not stopping very fast. I naively thought that maybe the front brakes had worn so far that the fluid level got to low and sucked in air. I added fluid and bled the system, all was well for a week or so. Today I jumped on the bike looked at the fluid level, it was in the bubble where I had left it and went down the block. by the end of the block the fluid was gone, even at full tilt to the left and rocked over a little bit. Anyway the fluid has the front of the engine covered and the right side plastic has noticeable trails behind the radiator. Needless to say I will not be taking my bike to work. Any ideas. I have searched and returned nothing.

The bad news. I want to fix the bike, but times are tight here for my wife and I as we bought a new to us home. I don't think we are going to be able to keep this bike. I might be able to scrounge the money around in a year or 2 but I think this one has to go. I love this bike and it saddens me deeply that I have agreed to this but it is the LT and the "Luxury" part is unfortunately a luxury I can't keep.

Please let me know of any Knowledge to the brake fluid leak and also let me know if anyone is interested in a 99' K1200LT Champaign, 73K miles new front and rear tire (Metzler 880's) new brake pads rear and everything else is pretty stock. The bike will not be for sale until leak is figured out and fixed unless the buyer wants to fix it.

I would check the break lines first. There have been several to break in the recent past. Mostly at the joint areas where the fittings meet the rubber hose. Most of these hoses are not overly expensive and it is usually a easy repair on the early LT without the linked breaks.

I agree, this is probably a relatively inexpensive fix. Since the fluid is on the front area of the bike it is not in the expensive area, the ABS system.

Nothing in front but brake lines and fittings. No expensive parts there other than the master cylinder at the brake lever, but if you see no fluid at that area check all the lines and fittings. I assume the front calipers are dry?

brake lever area was dry, and the right caliper was wet but that was due to extensive drips from everywhere. Lines were wet plastic was wet fender was wet. There is no way that the caliper leaking could have caused lines that are straight up from it to get wet so I assumed that the lines were the cause. I did not know if this was a regular problem or not. I used some simple green to clean up the area rinsed it off and found that when I squeezed the brake lever it leaked out underneath the engine, running down the plastic and engine. Need to get the plastic off of it to get a better look.

Side note, I am not selling it because of the brake problem. My wife and I need the money to put fix misc. items in the house.

It's the flex lines that are just above the calipers.. Just go to a Hose shop.

Or one of the flex lines above those...There's a couple of them up there.

They can make you some out of Braided steel hose for about 20 bucks each.
That's what I did on my rear line behind the master cylinder and it about doubled the stopping power.
It's an easy and relatively inxpensive ( As far as the LT goes.) fix.

Hell, don't sell her just because of this. Wait till something really expensive fails.

Good Luck

Something expensive did break in the house, gotta come up with money for the furnace and AC and all the installation fees. I don't have the money laying around right now because of the purchase of the house and now I need heat before it gets colder, and it will get much colder here

I'd rather have heat during the winter where you live than a motorcycle in the winter where you live.

Its in the classifieds for $6000 OBO. I will admit I am flexible on it, because of my need for the money. I thought for sure this would catch dshealey. I have seen you guys make comments on him before. You would think the LT "god" would have his own bike, well here it is.
