Emergency Brake doesn't stay there when step on

Check the release mechanism to see if it is not returning or stuck or broken.

I think it is push on and push off. The pedal will come back up each time so the brakes might be working ok. When you push the pedal down and take your foot off, does the brake light on the dash remain on? THEN if you push the pedal again and take your foot off the pedal, it will go out? That is the way it is supposed to work!!! Did you get the owners manual? If so check it to see how it works exactly. I might be totally wrong.
