OK, this is the update: I rebuilt the calipers, replaced the pads and rotor and flexable brake lines and the e-brake shoes and springs ($280). I went to bleed the rear brakes with DOT 4 fluid and the pump the pedal process didn't work. I then got out my pressure bleeder and hooked up to the steel lines at the master cylinder. That did work but I got an inch of air in the lines when I disconnected and reconnected to the master. I tried the brake pedal pump method again but again it did not work. I then attached the pressure bleeder to the cap of the master and tried some low pressure bleeding. That didn't work and made a big mess when it leaked. I got to thinking and decided to pull the master. I see no visible problem with it but the piston actuator may need some adjustment. I need to determine if the piston is being allowed to return all the way. If that's OK, I will take the master apart. I am bound and determined to fid the root cause and will update again soon
