Ahh brakes, so much fun. How far can you pull back the lever? Do you still have the original brake line?

First, remove the caliper from the mount. Now pull the bolt out for the arm. Clean it well and put grease on it. Put the bolt back in and make sure the arm moves freely. Once you got that, it is time to check the caliper. Did you clean it? If not, then you will need to. DOT3 fluid attracts moisture and builds up crud that makes the piston stick. Also, the brake pad my now be contaminated by the blue stuff. That may explain the soft brake with hard lever. You will probably want to replace them but try spraying them with brake cleaner spray and see if that helps.
