Its the same as the master brake cylinder . You only prime them which is (optional). You need to bleed the slave cylinder on the transmission just as you bleed the brake calipers. You can do it assisted by a friend , ------(1) open nipple 2) have friend depress clutch and hold 3) close nipple 4) pump clutch 5) repeat 1-4 until done . ---- Or a Bottle with a house on the nipple with brake fluid in it Or the auto store sells a self bleeding kit ( same thing as bottle).
