brake problems

my front brake locked up on me a couple weeks ago took the master cylinder apart got a new plunger for it an put everything back together the exact way it came out.... but i cant get it to bleed or pump up or move fluid through the master cylinder anyone have any ideas what that could be?

I have best results removing the caliper & outside pad, compress the inner pad with a small c-clamp, then pushing fluid ( and air) from the bottom bleeder, up out the handlebar master cylinder. Use of a 2 oz feed store plastic syringe works for me.

It's also a good idea to keep the brake line lower than the master cylinder while bleeding. Air can get trapped in the line where it curves up and then down towards the MC.
