heres my how to,hope this helps-all i used was 1 rear brake cable,an old gyro slug,2 cable stops + a g-sport nipple clamp (you could use 1 clamps you get with a hombre brake also)
to start with i used a slug from an old gyro cable as stops at the top of the stem- also make sure the outer cables are both cut to the same length
feed the cable through to the brake as normal
then i put an old cable stop up to the brake bolt plate -the put the outer cable on +threaded the cable into 1 side of the brake
then over to the other side of brake
and back up the other side-use the same process as previous -again making sure outer sleaves as same length
and finally up to the other lever-pull cable tight +i used a g-sport nipple clamp to hold cable in lever
once all tightened up you can use adjusters to get correct tension
forgot to say make sure you lube the cables well as you put together
if its on a new bike with a large hollow aheadsetbolt you could just have 1 cable fed all the way through +not have to mess about with cable stops
