master cyl pushrod

what you can also try is
put the master back in place
reinstal the push rod back to the pedal
grab the pedal and pull as hard as you can

it work for me

Be careful using this method. When the rod does pop loose, the brake pedal will come up quickly and bend the **** out of your brake light switch bracket. Just did this!! It does work, but I would use restraint and just jerk the pedal, not pull with all of your might!!

Edit: I guess I should have read all the way to the bottom of the thread before posting
