Well I finished installing the braided stainless front brake lines on my BMW K1100LT, I've got new lines for the rear as well, but it became such a PITA to do the front that I decided I'll do them later.
Because the bike has ABS, the flexible line from the MC goes down under the frame top tubes, then connects with a hard line into the ABS modulator beside the rear wheel, then another hard line comes out just in front of the fairing above the radiator, where it is connected to another flexible line that goes down to a splitter on top of the fork brace, where two more flexible lines carry the fluid to the calipers.
Due to the 6 feet or so of brake lines travelling around the perimeter of the bike, it is necessary to bleed the modulator first to remove any air trapped in the three feet of line between the MC and the modulator, and then at each caliper after that. Even with my mighty new Mityvac tool, it took ages to do.
All seems to be working well now, this job came about due to a problem I had where the brakes would stay on even after releasing the lever, until the bike came to a halt. Needless to say, it was pretty scary, and I was abused by a couple of drivers for pulling up to a dead stop 30 feet from a set of traffic lights with nothing in between me and the lights more than once, so it was a toss up whether the bike would kill me, or an irate driver. Luckily enough, we don't have that many gun toting motorists here in Oz, or I probably wouldn't have a head by now.
So finally, the BMW K1100LT is a wonderful bike, capable of criss-crossing any continent in the world in absolute comfort and style, 500 mile days are a walk in the park, and 1000 mile days are a possibilty if you can stay awake that long. However, the problem of brake lines on 17 year old BMW's internally collapsing is starting to become common, so if anyone is contemplating buying one of these bikes as a winter alternative to their trusty CB750's, beware, if the lines haven't been replaced it's a big job, so either walk away, or be prepared to spend a couple of hundred bucks and at least one full day to fix it.
BTW, the braided stainless lines that I bought from "Motobins" in England, were much cheaper than the OEM rubber lines from BMW. Cheers, Terry.
