1) Put everything on paper. Resist the temptation to judge your ideas as you write. Let yourself throw up on paper, and then edit your ideas later.
2) Divide your brainstorming over several days. This allows you to return to your ideas with a fresh eye. Avoid marathon sessions.
3) Play word association.
4) Look up dictionary definitions of words related to your topic. I am frequently surprised by dictionary definitions, especially of common words that I assume I understand. Dictionary definitions can stimulate other thinking strategies.
5) Talk out your ideas with a friend. Having to verbalize your ideas out loud to someone else will motivate you to distill your ideas in a coherent manner.
6) Turn off the Internet. Music is fine, but otherwise, brainstorming should be: you, a piece of paper, a pencil, and your thoughts.
