It sounds like you may have air getting into one of the brake lines. Check all four of the flexible lines at each wheel for cracks or leaking. Then check all the lines where connections are made. If all of those are ok, then check the caliper pistons and/or wheel cylinders for leaks. If all checks out, try picking up a vacume speed bleeder from Auto Zone. This will help pull all the air out of the system.
