Help, I have a 98 k1200rs. The flexible brake hose coming off the master cylinder for my front brakes failed. I replaced it with one from the dealer and now im trying to bleed the brakes without any success. After opening the bleeders on either the abs unit or the front wheel calipers, I cannot get fluid to flow thru the lines. When I pull on the front brake lever, it just stops. I am able to get fluid out of the rear brake caliper without any problem. What am I doing wrong ?
