Hi, just done one in the last 2 days, i just fitted the slave and put the box back on, i took the bleed nipple out completely for 30 mins then put it back in and bled it, didn't take long to bleed it up, an easier way is to get one of the self bleeding kits, its just a bottle you fill with brake fluid and it connects to your tyre and the top of your resevoir, then just undo the bleed nipple, 10 seconds later all done, the kits are about a tenner, top piece of kit
