You need to bleed the brakes, there is air in the lines. Then you need to check for where the leak is, even if you don't believe you have one. If you have front drums, you for sure have a leak. If you have disc brakes, it is possible that the pads are so worn that the cylinder got that low. If you don't see fluid leaks at the flexible brake lines or wheel cylinders, pull the master away from the booster and see if there is fluid leaking out the back of the master.
