I have a new Pro Italia Big Bore Clutch Slave, which I think is the Evoluzione Competition model rebadged, and a Brembo gold 996 type adj Master. I have been losing total clutch lever only appearing after 2 hours of hard riding and it returns to normal with a pump or two. The slave and the lines are new and have been bled numerous times so I suspect the master has gone bad as it is the oldest link. Any ideas? Does anyone know if it maters what master is used with this slave and if so what one to get? I remember reading somewhere there could be a mismatch somehow. Thanks men!
