So I changed to a steel braided line front brake line, but it won't bleed now? I can pump the lever for hrs and it won't build up any pressure to bleed them. I tried everything. All the bolts and bleeder valves are closed, but this one has me stumped. I even went back to the stock cable and it still doen't work now. I had a front brake before going through this exercise, now I can't even get it back to what is was before I started.
