I'll throw this out without checking any of the available written procedures but I believe it's correct. You need a 1010 (10 mm thread x 1 mm pitch) speed bleeder for one line. This also works on the clutch line. You also need some kind of 7mm to reach the recessed zerks on the right and left sides of the control box. I used a 7 mm ignition wrench and bent it at a 90 deg angle right at the box head. Then ground the the box down until it would fit and used a pair of vise grips to hold it. If you have a way to do it a better solution is the weld/braze a socket on the end so you can use a rachet to drive it. The vise grips are kind of clumsy.
If you look in the how-to archives I'm sure there's a good procedure.
