Gi'me a brake! front drum question

I don`t know about drum brakes but on disc brakes sometimes the bleeders themselves can get clogged up. Try giving them a good cleaning and blowing them out with air. I`d remove a bleeder valve one at a time and see if fluid will come out with gravity, if not give a little push on the pedal to see if fluid comes out. Start at the bleeder and work your way back to the master cylinder, systematically assuring that you have fluid flow. HTH.
