I work at a bike store and got digg and found part to make a hand brake kit. I works ok, just need to make the mount higher and i think it be great just little weldin. All you need is a mount to hold a bike cable, brake cable, brake handle, and the stop bolt.

Pics of 2 setups, mine and wiggs.

 

just a idea... to improve a little mabye.. Weld or clamp a straight peice to the part of the rear brake going up to make it taller so it will get more leverage and be easier to pull and will make the brake catch easier. here is a pic cause i not good at explaining... Or drawing on pics as you will see LOL

 

yea that was talked about doing when we got them done. Probly going to happen it works good for wheelies contol. the problem with add to it, it also make the amount of pull you need more too.

 

so does it work as good as the foot brake? i keep flippin when i try to do seat standers/spreaders and i think i need one of those till i get better

 

yea i work good, not as power full as the foot, since your not as much lever as the foot, but works great for wheelies.

 

Time to go home and rape the mountian bike for its brake parts!
