I would talk to the tech guy . The master may not be correct for your rear brake cylinder. Most places sell generic masters mostly for cars . If your rears are to large there may be a pressure differential between the disc and drum brake for a fraction of a second causing it to believe there is a leak in the rear circuit.

Maybe change out the portioning valve it could be defective.
