branch rebase and push

Hello,

Can I push a branch after rebase?
I got a error message:
   error: remote 'refs/heads/br' is not a strict subset of local ref
   'refs/heads/br'. maybe you are not up-to-date and need to pull first?

It worked fine if I did:
  $ git checkout -b br
  $ git pull . master
  $ git checkout master
  $ git pull
  $ git push

But I got above error message if I did:
  $ git checkout br
  $ git rebase master
  $ git checkout master
  $ git pull
  $ git push

Thanks. namsh
