I plugged the two ports leaving the ABS for the front brakes, so fluid was just going to rear. Tried the pedal and discovered I had a hard pedal. I am now thinking that the front driver's caliper is bad. I will replace that and both front brake hoses and a new bleeder screw on the passenger side and see what that does. Master cylinder and ABS must not be problem since I got the hard pedal after plugging.
