fill the cylinder and gravity bleed and leave all the nipples cracked.
Next go to your local parts place and by a brake bleader that connects to a compressor read and learn how to use it,mine cost a hundred bucks and I have long since got my monies worth of use out of it.
An old mechanic told me that pumping the system is fine in an emergency but it tends to push all the #### thru the master and can screw up the cylinder and wheel cylinders,pumping the system is harsh but vacuuming is a gentle way of doing it.
