Nosepieces and shackles

[Nick Turley]

You can of course fit semi girling hubs to the earlier axle and then use normal radius arms which give a bit of adjustment.
It also preserves the original"look".
It is quite good to box the earlier radius arms up for strength if you are going to be enthusiastic with the brakes.
 Also I usually weld the gaps up between the ends and the arm as the rivets can come loose with a lot of milage.
Hope that is useful.
