Wilwood 4 piston calipers

[Miss Information]

I have Wilwood 4 piston calipers with 4 bleed nipples and only one pipe in. How many bleed nipples do I need to use? The highest one, the highest two or ????

Any help would be much appreciated.

Thanks.

Use them all starting with the one furthest away from the feed pipe.
