Sounds like you need a bleed first. After that press your foot on the peddle, it should stay where it is with constant force. If is slowly moves down, you have a leak somewhere. It would probably be master cylinder or brake calipers. Check for gunk on the inside of the wheels to find the leaky caliper. Don't get brake fluid on your paint. Over time it will eat it up like paint remover.
