I bought a 2005 k1200lt about a year ago. The bike only had 5500 miles on it and had been kept inside an aircraft hanger. I currently have 7800 miles on it. I was out on a ride about a month ago and the brake fail light and triangle came on and would not go out after shutting off the bike and restarting it. I had the original brake lines so I bought new spiegler hoses,flushed and serviced. When I turn the key on the bike goes through the initial start up and I here the servo cycle then the triangle and brake fail light starts flashing. If I apply the front brake I here the servo, if I apply rear brake no servo. If I turn the key back off and apply the rear brake right when I turn the key on , the rear servo will come on until I release the rear brake and then it won’t come back on line. Sorry for the book I just wrote!! Appreciate some insight .
