is there a bleed nipple on your master cylinder??if there is you need to bleed the master clyinder first then move onto the slave clyinder....pump the pedal a few times to get the fluid around the system...then get some to hold the pedal down then you open the bleed nipple to let air an fliud out then close it an tell the person holdin the pedal to let it up an keep doin that until you get a constant stream of fluid an no air
