how do i prime and bleed the front breaks on my speedfight 2 50cc 04 plate?

just changed front disk and pads on speedfight 2. also taken calliper apart to clean it as i think one was sticking. the reason ive done all this is i had serious break judder when applying front break.BUT! i havent got the foggiest idea where to apply the break fluid and how to bleed the breaks. i was told also that i had to prime the resevoire. what does this mean and how do you do it. please could someone out there help me with this as i dont want to kill myself without propper breaks. many thanks.....
