2001 cr250 front brake

I am having a problem with my front brake. with the stock brake line I was experiencing a mushy feel. I changed the brake fluid and bled the system well. This didn't make much of a difference, so I purchased a steel braided brake line hoping that it would get rid of the mushy vague feeling. Still nothing. I can't figure out the problem and it is driving me nuts, the system is to simple to be this difficult to fix. I would really appreciate any help.

Thanks,

Ya I remember how solid it used to feel, that's why it's bothering me so much. What is back bleeding? I was gravity bleeding.
How much to rebuild the master cylinder? can I do it myself? and how can I tell if that is what needs to be done, is there some sort of test?

Thanks for the reply.
