It seems as though I'm manually bleeding my brakes every other month but now, I have virtually no pedal. I put on a new master cylinder a couple of months ago and pulled my rear drums and replaced them with discs some time ago. I get a good fluid-flow when I press the pedals with no indication of air. I've also checked for weeping along my lines. I'm thinking faulty M/C and wondering about replacing it. I am certainly open to suggestions in regards to repairs HELP!!!
