I have been trying to bleed the front brakes on my 05 450f. I have all the air out of the lines, at least I think I do. But the brakes still seem really spongy. I can pull the lever to my handlebars. Is there any certain way to bleed them so it will pump up the way it is supposed to? I have just been pumping the lever, holding in and loosening the bleeder screw, then tightening the screw back up and releasing the lever. I have done it quite a few times but still no progress.
