Vehicle had a clutch fade...no hydraulic pressure & cannot change gears. on 2008 Dodge Avenger

We fitted a new master cylinder, imported from America. After driving vehicle for 3 days, clutch fades & we have to bleed system. This has happened a few times, is there a special way of bleeding clutch? or is there another problem which we are not aware of relating to this particular model.....HELP!!!
