I think the brake bushes are 9/16" OD. You might want to drill slightly smaller, say 35/64" and ream to 9/16" to try to correct out of round drilling.
The accurate way of doing this would be to set the axle case up on a milling machine but it would have to be very large machine! Might be able to do it on a large, floor standing, very stout pillar drill. The problem would be chattering of the tool bit due to flexure of the axle case.
