I would take off your drums (if you have them of course) and check them out. If you do have drums, your shoes are probably worn down too far, which is why your wheel cylinder blew out. Replace everything, problem fixed!

If that doesn't work, double check all of your brake lines, any fittings, and just go over everything to make sure none of your fittings are leaking. The back side of your drum breaks tend to rust, and can break pretty easy or start to leak, so check that too!
