Hi Larry The problem occurs on both sides which are independent of each other so I reckon its something to do with the design or my setup. The Great Plains model has a resevoir integral with the master cylinder. I have the master cylinders mounted vertically in a toe/heel arrangment with the plunger downwards and bleeder at the top and maybe this affects the way the internal ports (?) compensate. It would really help if I knew how they work. I need a picture.
As you say, it is possible the plunger is binding and not free to travel back to its start position but equally there is no particular force like a spring or anything to do this. It must rely on residual pressure to return it. Maybe I'll pull one down and navel gaze it. It doesn't happen as a result of me applying and releasing brakes but rather after a period of sitting still......they sort up pump themselves up on their own!!......typical of my aircraft...a mind of its own.
